Notes

1. The seat fell vacant due to the death of sitting MLA Sadhan Pande on 20th February 2022. However, by-polls to the seat couldn't be held even after 6 months of Pande's death (according to Indian law) because BJP candidate Kalyan Chaubey filed an election petition in the Calcutta High Court alleging irregularities in polling & demanded a recount of votes. The Representation of the People Act, 1951 forbids holding any polls to the seat until any election petition concerning that seat hasn't been resolved at the court.^[7] On 29 April 2024, Choubey withdrew his election petition from the court, making way for by-poll to the seat.^[8]
