2021 by-polls

AITC MLA Sovandeb Chattopadhyay from Bhabanipur resigned after the election to allow Mamata Banerjee to contest a by-election in the constituency.[1]

In the beginning of September, the ECI announced that general elections for Jangipur and Samserganj assembly seats and by-election for Bhabanipur seat would be held on 30 September and votes would be counted on 3 October. The time limit for filing nominations was set from 6 September until 13 September for Bhabanipur only.[2][3][4] Mamata Banerjee filed hers on 10 September.[5][6] A total of 12 candidates contested in Bhabanipur by-poll.[7][8] Kishor enrolled himself as a voter from Bhabanipur, but he did not cast his vote.[9][10]

A total of 52 central forces companies were deployed to the three poll-bound Assembly constituencies' booths.[11][12][13][14] Section 144 was enforced in Bhabanipur on 28 September.[15][16] On the eve of polling, the Commission deployed an additional 20 companies of central forces in Bhabanipur.[17][18][19]

On 28 September, the ECI announced that remaining by-polls would be held on 30 October and votes counted on 2 November.[20][21]

On 30 September the first report of violence came from Samserganj, and Congress candidate Jaidur Rahaman was accused of carrying out a bombing in this constituency.[22] TMC activists raised "go back" slogans surrounding him while he inspected booths on polling day. Central forces were accused of kicking TMC leader Habibur Rahman, the outgoing councilor of Ward 20 of Dhulian Municipality under Samserganj Assembly.[23][24] Priyanka Tibrewal, BJP candidate of Bhabanipur, was accused of violating the ECI's model code of conduct by travelling across the area with many cars and people at once.[25][26] After she claimed to have caught fake voters, Firhad Hakim pointed out that as a candidate she had no right to check their identities.[27] BJP leader Kalyan Chaubey's car was allegedly vandalised in Bhabanipur and BJP blamed TMC for the act.[28] Police released CCTV footage of the incident, claiming it had nothing to do with politics.[29][30] BJP claimed that Chaubey was their candidate's election agent but according to Commission sources, he was the agent of a Hindustani Awam Morcha candidate. The vehicle he used to get to the polling constituency was not registered by the EC. BJP lodged a total of 23 complaints against TMC over the voting process in Bhabanipur, but the ECI dismissed all of them.[31] A total of 697,164 voters were eligible to cast their votes in the three constituencies.[32][33][34][35] The voter turnout for Samserganj, Jangipur, and Bhabanipur was recorded at 79.92%, 77.63%, and 57.09% respectively.[36][37]

Results were announced on 3 October, with TMC winning the three seats.[38] Mamata Banerjee won the Bhabanipur Assembly seat by a margin of 58,835 votes over the BJP candidate.[39][40][41] TMC led in all wards of Bhabanipur, including wards 70 and 74, where BJP led in the last assembly polls.[42] On the same day, TMC officially announced a list of candidates for upcoming assembly by-elections to four seats.[43]

The Model Code of Conduct was imposed in Nadia, Cooch Behar, Khardaha, and Gosaba.[44] The ECI initially deployed 27 companies of central forces for the remaining by-elections.[45][46] A week before the by-elections, an additional 53 companies entered the state.[47] Later, the ECI decided to deploy a total of 92 CAPF companies.[48]

On the last day of the Dinhata by-election campaign, Dilip Ghosh and Sukanta Majumdar met the deputy inspector general of police, Shailendra Kumar Singh, at the Border Security Force sector headquarters of Sonari in Cooch Behar. This was controversial because the Chief Minister could not even hold administrative meetings with Cooch Behar district officials, as the model code of conduct was in effect. Reacting to this, Hakim said "Recently, the Ministry of Home Affairs has increased the jurisdiction of BSF to 50 km.[49][50][51] Taking advantage of this, the BJP leaders went to pull the BSF chief over to their side." TMC lodged a complaint with the ECI.[52][53] A TMC deputy went to the district magistrate's chamber and complained that the BSF-BJP meeting had violated the model code of conduct.[54]

On polling day, central forces were accused of intimidating voters at booth 296 in Dinhata and some other booths in Kharadaha and Gosaba.[55][56] In Kharadha, the central forces prevented TMC candidate Sovandeb Chattopadhyay from entering a booth, who alleged that they unfairly demanded to see double vaccination certificates from voters. The problem was resolved after informing the matter to the presiding officer.[57][58] During the election campaign, Joy Saha, BJP candidate of Khardaha, used a picture of the deceased TMC leader Kajal Sinha in his campaign.[59] On election day, he claimed to have caught two fake voters red-handed, which was proven false. When he claimed to have caught a fake voter and BJP supporters started harassing the man, a fight broke out between the TMC and the BJP over the incident.[60] Joy Saha's personal security guards baton charged TMC activists, injuring the Sinha's son in the process.[61][62] Gosaba registered highest voter turnout among four constituencies.[63][64]

The results of the four constituencies was announced on 2 November, with TMC winning all seats.[65] TMC's Sovandeb Chattopadhyay and Subrata Mondal won Khardaha[66] and Gosaba,[67] respectively, by huge margins. Udayan Guha, who lost the Dinhata seat by a margin of 57 votes during the assembly election, won the seat in the bypolls by a margin of 164,089 votes.[68] TMC also won the Santipur seat, where Braja Kishor Goswami[69] was the TMC candidate, from the BJP by a considerable margin of votes.[70]
