The Trinamool Congress (TMC) is facing a significant internal crisis as approximately 20 of its 29 Lok Sabha members have decided to break away and form a separate bloc supporting the BJP-led National Democratic Alliance (NDA) government. This rebellion follows a similar uprising within the TMC's legislative assembly, where nearly 60 MLAs recently elected a new Leader of Opposition, bypassing the choice of party supremo Mamata Banerjee. Key figures in the rebellion include Kakoli Ghosh Dastidar, who has emerged as the bloc's leader after being removed as the chief whip, and Sukhendu Sekhar Roy, who resigned from the Rajya Sabha and the TMC, citing widespread corruption within the party. The rebel MPs, including notable members like Prasun Banerjee and Sharmila Sarkar, expressed their belief that aligning with the NDA reflects the people's mandate. Dastidar and others have criticized the TMC leadership for its handling of party affairs, claiming their decision was made after thorough discussions among colleagues. This split poses a serious threat to the TMC's unity and future, especially following its recent electoral losses in West Bengal.
