At least 188 constituencies witnessed the deletion of over 5,000 names after adjudication. Five years ago, the average number of voters in these 188 districts (where the winning margin in 2021 was 5% or less) was 2.02 lakh. A 5% margin suggests an advantage of around 2,475 votes.
In 2026, 44 of the aforementioned 188 seats shifted from the Trinamool Congress (TMC) to the Bharatiya Janata Party (BJP). Mamata Banerjee’s TMC reclaimed two from the BJP. One was secured by Humayun Kabir’s Aam Janata Unnayan Party (AJUN), while another in Darjeeling went to the Bharatiya Gorkha Prajatantrik Morcha (BGPM).
