It was the shifting away of the Muslim vote from the Left Front to the Trinamool Congress that brought Mamata Banerjee to power in 2011. About 15 years later, a split in the minority vote became one of the reasons why the Trinamool Congress lost power in 2026. 

The Muslim vote bank which remained steady with the Trinamool over the past several elections saw a spilt in the 2026 Assembly polls, with the Left-ISF alliance, the Congress and Humayun Kabir’s Aam Janata Unnayan Party (AJUP) spoiling the Trinamool party.
