About 20 Trinamool Congress (TMC) MPs are preparing to write to Lok Sabha Speaker Om Birla to seek entry into the BJP-led National Democratic Alliance [1].
This potential mass defection threatens the stability of the TMC in Parliament and signals a significant internal fracture within the party leadership in West Bengal.
Kakoli Ghosh Dastidar (TMC) is expected to lead the rebel faction [3]. The group of lawmakers intends to formally request a shift in alignment to the NDA, moving away from the current party structure [2].
The rebel MPs said they want to work with the BJP-led alliance to prioritize development [4]. They also said they want to oppose the current TMC leadership under Mamata Banerjee [4].
Reports indicate that these lawmakers are seeking separate seating within the Lok Sabha to reflect their split from the main party body [4]. The move comes as a direct challenge to the authority of the TMC leadership during a period of reported turmoil within the party [4].
The group consists of around 20 members of parliament [1]. This shift would provide a numerical boost to the NDA while depleting the TMC's influence in the lower house of India's parliament [2].
The development was reported on June 8, 2026 [2]. The lawmakers have not yet officially submitted the letter to Speaker Om Birla, but the preparation for the move is underway [3].

A defection of 20 lawmakers would represent a critical blow to Mamata Banerjee's legislative strength and party discipline. By aligning with the NDA, these MPs are not only shifting their political allegiance but are actively challenging the TMC's governance model in favor of the BJP's developmental agenda, potentially altering the balance of power in the Lok Sabha.
