The party has fielded Krishna Kalyani from the same seat in North Dinajpur district, which she won from Raiganj constituency on a BJP ticket in the 2021 West Bengal Assembly elections. He resigned as a member of the state assembly ahead of the recently concluded parliamentary elections and was fielded by the Trinamool Congress as its candidate from Raiganj Lok Sabha. Although he lost.

Same is the condition of Mukut Mani Adhikari also. Adhikari, who was also elected as the BJP candidate from Ranaghat-South constituency in Nadia district in 2021, has been fielded from the same seat. He had also resigned from the post of MLA before the Lok Sabha elections after being made the candidate by the ruling party from Ranaghat Lok Sabha seat. He also lost.

By-election for Maniktala assembly constituency has become necessary due to the demise of former Trinamool Congress MLA Sadhan Pandey.This time, Trinamool Congress has fielded Supti Pandey, widow of the late MLA.

However, the surprising choice of candidate was in the case of Bagda Assembly constituency in North 24 Parganas district, where the bypoll has become necessary as former BJP MLA Biswajit Das resigned ahead of the Lok Sabha elections. Trinamool Congress had made him its candidate from Bongaon Lok Sabha. Das also lost.

However, instead of re-nominating Das, the Trinamool Congress has fielded Madhuparna Thakur, daughter of current party Rajya Sabha member and former Lok Sabha member from Bongaon, Mamata Bala Thakur. Incidentally, Madhuparna Thakur is also the cousin of two-time BJP Lok Sabha member from Bengal and Union Ports, Shipping and Waterways Minister Shantanu Thakur.

Detailed data of assembly-wise results of the recently concluded Lok Sabha elections shows that the BJP is comfortably in position in three constituencies, Bagda and Ranaghat-South, while the Trinamool Congress is in a better position in just one seat.
