The '''Sixteenth Tamil Nadu Legislative Assembly Election''' was held on 6 April 2021, to elect [[Member of the Legislative Assembly (India)|representatives]] from the [[List of constituencies of the Tamil Nadu Legislative Assembly|234 constituencies]] in the [[States and union territories of India|Indian state]] of [[Tamil Nadu]]. The [[Dravida Munnetra Kazhagam]] (DMK) won the election, ending the decade-long reign of the [[All India Anna Dravida Munnetra Kazhagam]] (AIADMK). The DMK's leader [[M. K. Stalin]] became the eighth [[Chief Minister of Tamil Nadu]], and the 12th Chief Minister since the [[States Reorganisation Act, 1956|1956 reorganization]]. He replaced [[Edappadi K. Palaniswami]] of the AIADMK.

The poll was Tamil Nadu's first assembly election after the demises of the two most prominent [[Chief minister (India)|Chief Ministers]] in the state's modern history, [[J. Jayalalithaa]]—general secretary of the AIADMK, and [[M. Karunanidhi]]—president of the DMK, who died in 2016 and 2018 respectively. With the AIADMK winning the [[2016 Tamil Nadu Legislative Assembly election|2016 election]], Jayalalithaa became the Chief Minister and served for almost six months. Upon her death, [[O. Panneerselvam]] took charge as the Chief Minister, shortly after which Palaniswami was sworn-in instead in 2017, who served till the end of the fifteenth assembly's tenure. The [[Election Commission of India]] declared the election to the sixteenth [[Tamil Nadu Legislative Assembly]] on 26 February 2021.

The DMK continued its [[Secular Progressive Alliance]] (SPA) with the [[Indian National Congress]], the Communist parties and many others, and named Stalin as its candidate for the Tamil Nadu Chief Minister's Office. The AIADMK joined the [[National Democratic Alliance]] (NDA) of the [[Bharatiya Janata Party]], the [[ruling party]] of the [[Union Government of India]], with Palanisami as its Chief Ministerial candidate. The polling was held on 6 April 2021 under [[COVID-19 pandemic in India|COVID-19 guidelines]]. The state recorded a [[voter turnout]] of 72.81%. Surveys before and after the polls predicted the Stalin-led SPA to win the elections with a large margin. The votes were counted on 2 May 2021; the SPA amassed 159 seats, with the DMK alone winning in 133 constituencies, securing an [[Supermajority|absolute majority]]. The NDA won 75 seats, out of which 66 were of the AIADMK. The DMK formed the [[Government of Tamil Nadu]] for the sixth time. [[M. K. Stalin ministry|Stalin and his council of ministers]] were sworn in on 7 May 2021.

It was also the first time in [[1996 Tamil Nadu Legislative Assembly election|25 years]] that the DMK won a majority on its own.

==Overview==
The [[States and union territories of India|state]] of [[Tamil Nadu]] is divided into [[List of constituencies of the Tamil Nadu Legislative Assembly|234 assembly constituencies]], each of which elects a member (called an [[Member of the Legislative Assembly (India)|MLA]]) to represent it at the state's [[Unicameralism|unicameral]] [[State legislative assemblies of India|legislative assembly]], as per Article 168 of the [[Constitution of India]]. The [[Tamil Nadu Legislative Assembly]] convenes at [[Fort St. George, India|Fort St. George]], [[Chennai]]. The member that manages to receive the support of the majority of the members of the assembly (that is the Chief Ministerial candidate of the party that secures more than 50% of the seats), which is a minimum of 118 members, is appointed as the [[Chief minister (India)|Chief Minister]] of Tamil Nadu, who is the executive head of the [[Government of Tamil Nadu]]. The [[Governor (India)|Governor]] of Tamil Nadu, the state's ceremonial head, will invite the Chief-Minister-elect and his [[Council of Ministers]] to be sworn in, to lead the [[State governments of India|state government]] for a term of the next five years.

Tamil Nadu's partisan politics have been dominated by its two regional [[Dravidian parties|Dravidian]] parties, [[Dravida Munnetra Kazhagam]] (DMK) and [[All India Anna Dravida Munnetra Kazhagam]] (AIADMK), for the last 50 years (since [[1967 Madras Legislative Assembly election|1967]]). Each recognized party in India is given a polling symbol by the [[Election Commission of India]], an independent and neutral body of officers that conducts and regulates all the elections in the country. The DMK contests with the ''Rising Sun'' symbol, while the AIADMK contests with the ''Two Leaves''.

The legislative assembly of Tamil Nadu goes to polls alongside the legislative assemblies of three other Indian states, namely [[Assam]], [[Kerala]], and [[West Bengal]], and that of the [[union territory]] of [[Puducherry (union territory)|Puducherry]].

[[M. Karunanidhi]] of the DMK and [[J. Jayalalithaa]] of the AIADMK were two of the most important leaders in the state's politics. They have served as the Chief Minister of Tamil Nadu five times each. In the [[2011 Tamil Nadu Legislative Assembly election|2011 election]], the AIADMK under Jayalalithaa handily defeated the DMK headed by Karunanidhi. In [[2016 Tamil Nadu Legislative Assembly election|2016]], the Jayalalitha-led AIADMK retained its majority with 136 seats, while the DMK increased its strength to 98 seats.<ref>{{cite web|date=19 May 2016|title=Victorious Jayalalithaa hails people's faith in AIADMK|url=http://www.thehindu.com/elections/tamilnadu2016/tamil-nadu-assembly-elections-victorious-jayalalithaa-hails-peoples-faith-in-aiadmk/article8620740.ece?w=spa|work=[[The Hindu]]}}</ref> 2021's election of the sixteenth assembly election is the first state election after the deaths of Jayalalithaa and Karunanidhi, who died in 2016 and 2018 respectively.

==== Rise of V.K. Sasikala ====
Following Jayalalithaa's demise from [[cardiac arrest]] on 5 December 2016, [[O. Panneerselvam]] of the AIADMK became the Chief Minister of Tamil Nadu for the third time. The first two times he attained the post (21 September 2001 to 2 March 2002, and 28 September 2014 to 23 May 2015) was when Jayalalithaa was forcibly removed from office twice due to [[Disproportionate assets case against Jayalalithaa|the lawsuit against her]]. He served as the Acting Chief Minister during Jayalalithaa's hospitalization in 2016. However, soon after swearing-in, Panneerselvam rebelled against the influence of [[V. K. Sasikala]], a long-time friend and close associate of Jayalalithaa, inside the AIADMK party, and deemed her a threat to his Chief Ministership, exposing the factionalism inside the party. In a meeting of the party's general council held on 29 December 2016, the first meeting after Jayalalithaa's death, Sasikala was appointed as the party's general secretary.<ref>{{cite news|date=29 December 2016|title=V.K. Sasikala appointed as AIADMK general secretary|newspaper=The Hindu|url=http://www.thehindu.com/news/national/tamil-nadu/V.K.-Sasikala-appointed-as-AIADMK-general-secretary/article16957866.ece}}</ref> On 5 February 2017, all the MLAs of the AIADMK unanimously elected Sasikala as the Legislative Assembly leader of the AIADMK, making her the Chief-Minister-elect officially.<ref>{{Cite news|last=Jesudasan|first=Dennis S.|title=Sasikala set to become Tamil Nadu Chief Minister|language=en|work=The Hindu|url=http://www.thehindu.com/news/national/tamil-nadu/sasikala-set-to-become-tamil-nadu-chief-minister/article17197392.ece1?google_editors_picks=true|access-date=2017-02-27}}</ref>

On 6 February 2017, Panneerselvam submitted his resignation letter to then [[Governor of Tamil Nadu]], [[C. Vidyasagar Rao]], who accepted the resignation but instructed him to continue to functioning as Chief Minister "until alternate arrangements are made", awaiting the pending verdict of [[Disproportionate assets case against Jayalalithaa|the 18-year-long trial regarding the disproportionate assets of Jayalalithaa and Sasikala.]] Panneerselvam also claimed that he was coerced into resignation. Later in the evening, Sasikala met the Governor and laid claims to the Chief Ministership, by submitting the list of AIADMK legislators who back her. Reports stated Sasikala had those MLAs sequestered at a resort in [[South Chennai]].<ref>{{Cite web|last=Simhan|first=T. E.

On 14 February 2017, the [[Supreme Court of India]] pronounced Sasikala and her relatives guilty of criminally conspiring, laundering and amassing illicit wealth worth about {{INRConvert|66.44|c|year=1996}} in the 1990s, and sentenced them to serve a four-year jail term at [[Central Prison, Bangalore]], giving the convicts 24 hours to surrender.<ref name="shell">{{Cite news|last1=Ushinor|first1=Majumdar|title=What The SC Said About Jayalalithaa: She Was The Source Of Funds For Shell Companies|newspaper=[[Outlook India]]|url=http://www.outlookindia.com/website/story/what-the-sc-said-about-jayalalithaa-she-was-the-source-of-funds-for-shell-compan/297959|access-date=2017-02-15}}</ref> This restored ''[[in toto]]'' her earlier conviction in the case<ref name="toto">{{Cite news|last=Rajagopal|first=Krishnadas|title=Jayalalithaa, Sasikala criminally conspired at Poes Garden to launder ill-gotten wealth: SC|newspaper=[[The Hindu]]|location=[[New Delhi]]|url=http://www.thehindu.com/news/national/tamil-nadu/Jayalalithaa-Sasikala-criminally-conspired-at-Poes-Garden-to-launder-ill-gotten-wealth-SC/article17301596.ece|access-date=2017-02-15|archive-url=https://web.archive.org/web/20170214124736/http://www.thehindu.com/news/national/tamil-nadu/Jayalalithaa-Sasikala-criminally-conspired-at-Poes-Garden-to-launder-ill-gotten-wealth-SC/article17301596.ece|archive-date=14 February 2017}}</ref> delivered on 27 September 2014.<ref name="original">{{cite news|date=29 September 2014|title=Justice John D'Cunha: The no-nonsense judge who convicted Jayalalithaa|work=[[Firstpost]]|location=[[Bangalore]]|url=http://www.firstpost.com/india/justice-john-dcunha-the-no-nonsense-judge-who-convicted-jayalalithaa-1732877.html|access-date=2017-02-26|archive-url=https://web.archive.org/web/20160807225107/http://www.firstpost.com/india/justice-john-dcunha-the-no-nonsense-judge-who-convicted-jayalalithaa-1732877.html|archive-date=7 August 2016}}</ref> Proceedings against Jayalalithaa had been abated and dismissed on account of her death. The conviction effectively ended Sasikala's Chief Ministerial ambitions.

Following Sasikala's conviction, the Governor rejected her claims to become the Chief Minister of Tamil Nadu. In her ticking 24-hour surrender time-limit and capacity as the general secretary of the AIADMK, Sasikala convened the party's MLAs, who unanimously elected [[Edappadi K. Palaniswami]], a then supporter of Sasikala, as the new Chief Minister. She also appointed her nephew and former treasurer of the party, [[T. T. V. Dhinakaran]], as the party's deputy general secretary. Palaniswami as sworn in as the Chief Minister of Tamil Nadu the next day, replacing Panneerselvam.<ref>{{cite news|title=Governor accepts CMs resignation|website=[[Business Line]]|publisher=[[The Hindu]]|url=http://www.thehindubusinessline.com/news/national/tn-governor-accepts-resignation-of-cm-o-panneerselvam-and-his-council-of-ministers/article9523821.ece}}</ref>

==== Merger of AIADMK factions ====

On 23 March 2017, the [[Election Commission of India|Election commission of India]] designated the two factions separately; Panneerselvam's faction known as "AIADMK (PURATCHI THALAIVI AMMA)", while Dhinakaran-Palaniswami's faction known as "AIADMK (AMMA)". By-polls were announced at the [[Dr. Radhakrishnan Nagar]] constituency, which was vacated due to Jayalalithaa's death. Dhinakaran was named candidate by his faction. However, the Election Commission canceled the by-polls after evidence of large-scale bribing by the ruling AIADMK (AMMA) surfaced. On 17 April 2017, [[Delhi Police]] registered a case against Dhinakaran for allegedly attempting to bribe the Election Commission into giving the AIADMK's significant ''Two Leaves'' symbol to his faction. Dhinakaran was granted bail on the grounds that the police failed to identify the bribed officer.

In the following months, the Chief Minister had a fallout with Dhinakaran. Palaniswami pronounced Dhinakaran's appointment as deputy general secretary "invalid" on 17 August 2017, and ousted him from the party.<ref>{{Cite web|title=AIADMK merger stage set: TTV Dhinakaran ousted as ruling EPS faction fulfills rebels' demand|url=https://www.newindianexpress.com/states/tamil-nadu/2017/aug/10/aiadmk-merger-stage-set-ttv-dhinakaran-ousted-as-ruling-eps-faction-fulfills-rebels-demand-1641199.html|access-date=2021-05-05|website=The New Indian Express}}</ref> On 21 August 2017, it was reported that the Paneerselvam faction of AIADMK had decided to merge back with the Palaniswami faction, under the terms that Sasikala would be expelled from the party.<ref name="ccc">{{cite web|date=21 August 2017|title=Sasikala to be expelled from AIADMK, OPS settles for deputy CM|url=https://www.thenewsminute.com/article/sasikala-be-expelled-aiadmk-ops-settles-deputy-cm-67147|access-date=1 December 2018|website=The News Minute}}</ref> On 21 August 2017, both Palaniswami and Paneerselvam factions of the AIADMK reunited, with the leaders assuming co-leadership of the party. Panneerselvam sworn in as the [[Deputy Chief Minister of Tamil Nadu]], Finance Minister of Tamil Nadu and the coordinator of the AIADMK. Palaniswami was dubbed the deputy coordinator of the party. Mainstream media and publications suspected the involvement of the [[Bharatiya Janata Party]], the ruling party of the [[Union Government of India]], in the AIADMK's merger. This marked the first time the BJP began to play an influential role in the Tamil Nadu politics, acting as the mediator that united the two factions. Dhinakaran and his supporters continued to dub themselves the "real AIADMK".<ref>{{Cite web|date=2021-03-14|title=Will BJP break into Tamil Nadu this time?|url=https://www.deccanherald.com/specials/sunday-spotlight/will-bjp-break-into-tamil-nadu-this-time-961751.html|access-date=2021-04-08|website=Deccan Herald|language=en}}</ref><ref>{{Cite news|last=Ramakrishnan|first=T.|date=2017-09-12|title=Sasikala removed as AIADMK chief|language=en-IN|work=The Hindu|url=https://www.thehindu.com/news/national/tamil-nadu/sasikala-removed-as-aiadmk-chief/article19672590.ece|access-date=2021-05-05|issn=0971-751X}}</ref>

==== Withdrawal of support from government ====
On 22 August 2017, 18 MLAs of the AIADMK pledged allegiance to [[T. T. V. Dhinakaran|Dhinakaran]] and submitted letters to the Governor, expressing [[No Confidence|lack of confidence]] in Palaniswami and withdrawing their support to the Palaniswami-led government.<ref name="The Hindu 22 Aug 2017">{{Cite web|last=Jesudasan|first=Dennis S.|date=22 August 2017|title=19 pro-Dhinakaran MLAs withdraw support to Palaniswami|url=https://www.thehindu.com/news/national/tamil-nadu/day-after-merger-19-pro-dhinakaran-mlas-withdraw-support-to-cm/article19538882.ece|via=www.thehindu.com}}</ref> Immediately, those MLAs were expelled from the AIADMK. The [[List of speakers of the Tamil Nadu Legislative Assembly|Speaker]] of the fifteenth Tamil Nadu Legislative Assembly, [[P. Dhanapal]], also disqualified those MLAs from their offices, citing [[Anti-defection law (India)|the Constitution Act of 1985]], which prevents the instability caused by democratically elected representatives in India's legislatures shifting allegiance from the parties they supported at the time of election, or disobeying their parties' decisions at critical times, by rendering their seats vacant. This resulted in a long legal battle, at the end of which, the [[Madras High Court]], the highest court of Tamil Nadu, gave a verdict in the Speaker's favour and confirmed the disqualification of the 19 legislators. Following these events, Sasikala was expelled from the party on 12 September 2017, with her position as interim general secretary disputed and abolished. Instead, the late Jayalalithaa was named the eternal general secretary of AIADMK.<ref>{{cite web|date=12 September 2017|title=AIADMK sacks Sasikala, says Jaya is 'eternal general secretary'|url=https://www.deccanchronicle.com/nation/current-affairs/120917/sasikala-is-expelled-announces-aiadmk-after-general-council-meet.html|website=Deccan Chronicle}}</ref>

On 23 November 2017, the Election Commission of India granted the ''Two Leaves'' symbol to the Palaniswami-Panneerselvam led AIADMK, authorizing the faction as the original AIADMK, and announced by-polls to the vacant seat of Radhakrishnan Nagar on 21 December 2017. Dhinakaran contested in the constituency as an [[Independent politician|independent candidate]], and won the election with a huge margin, with around 40,000 votes more than his closest competitor. He became the first independent candidate in Tamil Nadu history to win a bypoll, claiming 50.32% of the total votes, defeating the ruling AIADMK and the opposition DMK.<ref>{{Cite news|last=S|first=Mohamed Imranullah|date=2018-10-25|title=Madras High Court upholds disqualification of 18 AIADMK MLAs|language=en-IN|work=The Hindu|url=https://www.thehindu.com/news/national/tamil-nadu/madras-high-court-upholds-disqualification-of-18-aiadmk-mlas/article25319074.ece|access-date=2021-05-05|issn=0971-751X}}</ref><ref>{{Cite web|date=2017-12-25|title=AIADMK hit, DMK rattled as TTV Dinakaran wins RK Nagar seat|url=https://indianexpress.com/article/india/ttv-dinakaran-wins-rk-nagar-bypoll-leaves-eps-ops-camp-red-faced-jayalalithaa-aiadmk-4997245/|access-date=2021-05-05|website=The Indian Express|language=en}}</ref>

==== Rise of Stalin ====
After Karunanidhi's demise on 7 August 2018, Karunanidhi's son and political heir [[M. K. Stalin]], who has served as the [[Deputy Chief Minister of Tamil Nadu]] and the [[Mayor of Chennai]], became the unquestioned president of the DMK. The Election Commission of India announced [[2019 Tamil Nadu Legislative Assembly by-elections|by-polls to 24 vacant seats in the state]], alongside the [[2019 Indian general election in Tamil Nadu|2019 Indian parliamentary elections]], which elects 543 members across India to its [[lower house]], the [[Lok Sabha]]. The DMK-led [[Secular Progressive Alliance]] (nationally, [[United Progressive Alliance]] headed by the [[Indian National Congress]]) swept Tamil Nadu in the Lok Sabha elections, winning a landslide 38 seats out of [[List of constituencies of the Lok Sabha#Tamil Nadu (39)|the state's 39 parliamentary constituencies]]. The AIADMK, which contested the election in an alliance with the [[Bharatiya Janata Party|BJP]] and the regional [[Desiya Murpokku Dravida Kazhagam|DMDK]], won only one seat ([[Theni (Lok Sabha constituency)|Theni]]).<ref>{{Cite web|date=2019-05-23|title=Anti-Modi wave in TN; DMK alliance wins 37 of 38 seats|url=https://www.deccanherald.com/lok-sabha-election-2019/anti-modi-wave-in-tn-dmk-alliance-wins-37-of-38-seats-735651.html|access-date=2021-05-06|website=Deccan Herald|language=en}}</ref> This marked a huge shift from the [[2014 Indian general election|2014 parliamentary elections]], in which the AIADMK had won 37 seats solo, whereas the NDA won two and the DMK none.<ref>{{Cite web|title=2014 Lok Sabha elections — Results|url=https://www.webcitation.org/6PfWDNtfY?url=http://eciresults.ap.nic.in/PartyWiseResult.htm|url-status=live|access-date=2021-05-06|website=www.webcitation.org}}</ref> In the by-polls, out of the 24 formerly AIADMK seats in the state assembly, the Stalin-led DMK won over 13 seats while the AIADMK won 10, indicating a shift in the political mindset of the state's voters. Although the incumbent AIADMK government lost 13 of its seats to the opposition party, the 10 retained seats (with new MLAs to represent them) were enough to maintain the AIADMK's absolute majority at the Legislative Assembly.

==== Formation of AMMK ====
The expulsion of Sasikala and her family from the AIADMK led to the formation of new party, [[Amma Makkal Munnettra Kazagam]] (AMMK), headed by [[T. T. V. Dhinakaran|TTV Dhinakaran]] as the general secretary with the goal of obtaining control of the AIADMK.<ref name="DMK">{{cite web|title=Sasikala will be General Secretary, I will be Deputy General Secretary of AMMK, says TTV Dhinakaran,she was looted the general public fund.|url=https://www.indiatoday.in/india/story/sasikala-will-be-the-general-secretary-and-i-will-be-the-deputy-general-secretary-of-ammk-says-ttv-dhinakaran-1194718-2018-03-21|website=India Today|language=en}}</ref> In January 2021, [[V. K. Sasikala|VK Sasikala]] was released from jail after completion of her prison time. In February 2021, she announced her intention to actively involve herself in the state's politics. Nevertheless, on 3 March 2021, she announced her decision to quit politics, to everyone's surprise.<ref>{{cite web|title=V K Sasikala says she is quitting politics ahead of Tamil Nadu polls|url=https://www.livemint.com/politics/news/v-k-sasikala-says-she-is-quitting-politics-ahead-of-tamil-nadu-polls-11614787477346.html|website=Livemint|language=en}}</ref>

=== Key Issues ===

=== Analysis and trends ===

* In Northern Tamil Nadu, the [[Chennai metropolitan area|Chennai Metropolitan Area]] and its surroundings proved to be a stronghold of the DMK. The DMK-led SPA completely sweeped all of the constituencies located in [[Chennai district|Chennai]], [[Tiruvallur district|Thiruvallur]], and [[Kanchipuram district|Kanchipuram]] districts.<ref>{{Cite web|title=TN Election Results: These are the regions that helped DMK seal their victory|url=https://www.newindianexpress.com/states/tamil-nadu/2021/may/02/tn-election-results-theseare-the-regions-that-helped-dmk-seal-their-victory-2297592.html|access-date=2021-05-13|website=The New Indian Express}}</ref> While facing tough competition in other parts of the North, the DMK bagged 64 of the region's 78 seats, overcoming the polarization between the AIADMK and the DMK that existed in the region in the 2016 election. The region expressed a strong anti-NDA trend, with the results indicating that the AIADMK did not benefit much from the its alliance with the [[Pattali Makkal Katchi|PMK]] and the 10.5% internal reservation that was granted to the [[Vanniyar]] community within the Most Backward Community (MBC) [[Reservation in India|quota]].<ref>{{Cite news|date=2021-05-03|title=DMK makes a clean sweep in northern Tamil Nadu|language=en-IN|work=The Hindu|url=https://www.thehindu.com/news/national/tamil-nadu/dmk-makes-a-clean-sweep-in-northern-tamil-nadu/article34468366.ece|access-date=2021-05-13|issn=0971-751X}}</ref>
*The politically sensitive Central Tamil Nadu and [[Chola Nadu|Kaveri delta region]] exhibited an overwhelming support for the SPA, with the AIADMK-led NDA winning only four out of the region's 41 seats. The DMK was met with victory in all the seats of [[Tiruchirappalli district|Tiruchirappalli]], [[Perambalur district|Perambalur]], [[Ariyalur district|Ariyalur]] and [[Mayiladuthurai district|Mayiladuthurai]] districts, crucially. The resentment that prevailed amongst the region's farmers over the former AIADMK government's inability to resolve agricultural problems in the region has been cited as a reason.<ref>{{Cite web|title=TN Election results: Good harvest for DMK in Delta region|url=https://www.newindianexpress.com/states/tamil-nadu/2021/may/03/tn-election-results-good-harvest-for-dmk-in-delta-region-2297731.html|access-date=2021-05-13|website=The New Indian Express}}</ref>
*Except [[Madurai district]], which was equally split between the AIADMK and DMK, much of Southern Tamil Nadu swinged towards the DMK alliance, an anti-incumbent trend compared to 2016, in which the Jayalalithaa-led AIADMK (without the BJP) had sweeped most of the region's seats, except [[Kanyakumari district]], which remained as an SPA stronghold. The region also gave the DMK its highest victory margin ever, with over 130,000 votes in [[Athoor (state assembly constituency)|Athoor constituency]] where its senior leader [[I. Periyasamy|I. Periasamy]] defeated the PMK candidate.<ref>{{Cite news|last=Srikrishna|first=L.|date=2021-05-03|title=DMK makes gains in south T.N.|language=en-IN|work=The Hindu|url=https://www.thehindu.com/news/national/tamil-nadu/dmk-makes-gains-in-south-tn/article34468335.ece|access-date=2021-05-13|issn=0971-751X}}</ref>
*The AIADMK maintained its traditional sway in Western Tamil Nadu, popularly known as [[Kongu Nadu]], where the NDA won more than 70% of the constituencies. Most notably, the NDA won in all the constituencies of [[Coimbatore district|Coimbatore]] and [[Dharmapuri district|Dharmapuri]] districts.<ref>{{Cite news|last=Prasad|first=K. v|date=2021-05-03|title=Western Tamil Nadu remains an AIADMK fortress|language=en-IN|work=The Hindu|url=https://www.thehindu.com/news/national/tamil-nadu/western-tamil-nadu-remains-an-aiadmk-fortress/article34468324.ece|access-date=2021-05-13|issn=0971-751X}}</ref>
*The [[List of cities in Tamil Nadu by population|cities of Tamil Nadu]] fuelled the DMK's victory in the election. 2021 exposed "a clear [[Rural area|rural]]-[[Urban area|urban]] divide" in the voting patterns of the state. Trends showed that DMK performed very well in the urban centres than the AIADMK. There are 154 rural, 30 [[semi-urban]] and 50 urban constituencies in the state. The DMK alliance won 40 of those urban seats, 96 of the rural seats and 23 of the semi-urban seats. Of the 75 seats the AIADMK alliance won, 58 were in rural areas, with only seven in semi-urban and 10 in urban centres. The SPA's strike rate was 80% in urban seats, 76% in semi-urban seats and 62% in rural seats, whereas the NDA's strike rate was 37% in rural seats, 23% in semi-urban seats and 20% in urban seats.<ref>{{Cite web|date=May 4, 2021|title=40 out of 50: Cities fuelled DMK win |url=https://timesofindia.indiatimes.com/city/chennai/40-out-of-50-cities-fuelled-dmk-win/articleshow/82380517.cms|access-date=2021-05-13|website=The Times of India|language=en}}</ref>

== Reactions and aftermath ==
[[Palaniswami ministry|Palaniswami and his ministers]] resigned on 3 May 2021, submitting their papers of resignation to [[Banwarilal Purohit]], the [[Governor of Tamil Nadu]].<ref name=":2">{{Cite web|title=Stalin expected to take oath on May 7; Udhayanidhi unlikely in 'younger' cabinet|url=https://www.theweek.in/news/india/2021/05/03/stalin-expected-to-take-oath-on-may-7-udhayanidhi-unlikely-in-younger-cabinet.html|access-date=2021-05-04|website=The Week|language=en}}</ref> During the early hours of the same day, DMK president Stalin paid respects at the memorial of his father and five-time Chief Minister, [[M. Karunanidhi]]. Speaking to the journalists gathered there, Stalin stated that he will be sworn in as the Chief Minister in a simplistic ceremony that may be held at the [[Raj Bhavan, Chennai|Raj Bhavan]], the Governor's residence. He underlined that the DMK will form the government for the sixth time in Tamil Nadu, and will follow the footsteps of Karunanidhi. Stalin added that the DMK's governance "will be such that those who had voted for the party will feel happy voting for it, and even those who did not vote would regret their decision to not have voted for the party".<ref name=":1" />

After the resignation of Palanisami's administration, officials of the [[Tamil Nadu Public Works Department|Public Works Department]] began resetting the [[Fort St. George, India|Tamil Nadu Secretariat]] to prepare the campus for the new government under Stalin. The Chief Minister's Office returned all the files to the departments concerned, with the office quarters white-washed and name-boards of former ministers taken down.<ref>{{Cite news|last=Jesudasan|first=Dennis S.|date=2021-05-04|title=Preparations under way at the Secretariat to host DMK government|language=en-IN|work=The Hindu|url=https://www.thehindu.com/news/national/tamil-nadu/preparations-under-way-at-the-secretariat-to-host-dmk-government/article34475643.ece|access-date=2021-05-04|issn=0971-751X}}</ref>

Politicians, celebrities and government officials across India congratulated Stalin on his victory. The out-going Chief Minister Palanisami congratulated Stalin, tweeting: "My best wishes to M.K. Stalin who is going to take oath as Tamil Nadu Chief Minister". In another tweet, Stalin thanked Palanisami and sought his cooperation for "building the best Tamil Nadu".<ref name=":1">{{Cite web|title=Outgoing CM Palaniswami congratulates Stalin, who responds seeking EPS' ideas and cooperation|url=https://www.wionews.com/india-news/outgoing-cm-palaniswami-congratulates-stalin-who-responds-seeking-eps-ideas-and-cooperation-382488|url-status=live|access-date=2021-05-04|website=[[WION (TV channel)|WION]]|language=en}}</ref> [[Narendra Modi]], the [[Prime Minister of India]], tweeted that he will work with Stalin to enhance the nation's progress, fulfill the regional interests of Tamil Nadu, and fight the [[COVID-19 pandemic]].<ref>{{Cite web|date=May 2, 2021|title=PM Modi congratulates Mamata, Vijayan, Stalin for poll win|url=https://timesofindia.indiatimes.com/india/pm-modi-congratulates-mamata-vijayan-stalin-for-poll-win/articleshow/82358407.cms|access-date=2021-05-04|website=The Times of India|language=en}}</ref>

On 10 May 2021, the newly elected AIADMK MLAs convened to choose the new [[Leader of the Opposition]], an important post equivalent to a cabinet minister. The meeting was inconclusive, with both Panneerselvam and Palaniswami staking claims to the post, while their supporters hurled charges against each other. This included a prolonged quarrel between the two sections of the party outside the party's head office, causing unrest. Supporters of Palaniswami believed that he should be the Leader of the Opposition due to the party's good performance in the election in [[Kongu Nadu|western Tamil Nadu]], the region he hails from; whereas, Panneerselvam's supporters felt that the party fared poorly in other regions of the state due to Palaniswami's wrong policies during his Chief Ministerial tenure.<ref>{{Cite news|last=Jesudasan|first=Dennis S.|date=2021-05-08|title=AIADMK unable to decide on Leader of Opposition post|language=en-IN|work=The Hindu|url=https://www.thehindu.com/news/national/tamil-nadu/aiadmk-unable-to-decide-on-leader-of-opposition-post/article34510412.ece|access-date=2021-05-08|issn=0971-751X}}</ref> Eventually, Palaniswami was elected as the Leader of the Opposition.<ref>{{Cite news|date=2021-05-10|language=en-IN|work=newindianexpress|title=Edappadi Palaniswami elected as Leader of Opposition in Tamil Nadu Assembly|url=https://www.newindianexpress.com/states/tamil-nadu/2021/may/10/edappadi-palaniswami-elected-as-leader-of-opposition-in-tamil-nadu-assembly-2300755.html}}</ref>

After MNM performed unfavorably in its first-ever election, many officials and candidates resigned from the party, such as its vice president Dr. Mahendran, Muruganandam,  C K Kumaravel. Mahendran said that "the attitude of Kamal Haasan towards the growth of the party has not been changed even after facing huge loss in the Tamil nadu assembly election". He cited the presence of "Sankhya solutions" in the party and added that Haasan is being misguided. Others cited "personal reasons".<ref>{{Cite web|date=May 13, 2021|first=Akshaya|last=Nath|title=After VP, 2 more members of Kamal Haasan's MNM resign from party|url=https://www.indiatoday.in/india/tamil-nadu/story/2-members-kamal-haasan-mnm-resign-party-1802297-2021-05-13|access-date=2021-05-14|website=India Today|language=en}}</ref>

=== Formation of government ===
On 3 May 2021, [[Durai Murugan]], the general secretary of the DMK, called for a meeting of all the party's newly elected [[Member of the Legislative Assembly (India)|MLAs]] on 4 May 2021, at 4 PM, in Anna Arivalayam (the DMK headquarters, [[Chennai]]). In the meeting, the 133 MLAs formally extended their support to Stalin's appointment as the DMK's head at the Tamil Nadu Legislative Assembly, making him the Chief-Minister-elect. [[M. K. Stalin ministry|Stalin's council of ministers]] and their allocated departments were revealed on 6 May 2021. The Stalin administration took charge on 7 May 2021, sworn in by Governor Purohit, in a ceremony at Raj Bhavan.<ref>{{Cite web|date=2021-05-06|title=Stalin swearing in as Tamil Nadu CM tomorrow; this is what his cabinet will look like|url=https://indianexpress.com/elections/m-k-stalin-to-be-sworn-in-as-tamil-nadu-cm-on-friday-cabinet-to-have-34-ministers-7304664/|access-date=2021-05-06|website=The Indian Express|language=en}}</ref> Stalin became the eighth Chief Minister of Tamil Nadu, and the twelfth Chief Minister since [[States Reorganisation Act, 1956|the linguistic reformation of the state's boundaries in 1956]].<ref>{{Cite web|last=Saxena|first=Prasanth|date=2021-05-07|title=Finally, son rises in Tamil Nadu as Stalin becomes Chief Minister|url=https://thefederal.com/tamilnadu-elections-2021/finally-son-rises-in-tamil-nadu-as-stalin-becomes-chief-minister/|access-date=2021-05-07|website=The Federal|language=en-US}}</ref>
