A faction of 58 lawmakers [1] has broken away from the Trinamool Congress to challenge the leadership of Chief Minister Mamata Banerjee.

This internal rebellion threatens the stability of the state government and puts the party's official electoral symbol at risk of being split or lost. The movement comes in the wake of the party's defeat in the 2024 West Bengal Assembly elections.

The rebel group is led by Ritabrata Banerjee. In a significant shift in legislative power, the Speaker has recognized Ritabrata Banerjee as the Leader of the Opposition. The dissident group claims to be the "real TMC," signaling a legal and political battle over the identity and assets of the party.

Further instability emerged as Kolkata Mayor Firhad Hakim resigned from his post. This resignation is viewed as a sign of deepening fractures within the party's urban stronghold, a move that may encourage more defections from the remaining loyalists.

The rebellion was triggered by widespread dissent following the 2024 election losses. Members of the rebel faction have expressed dissatisfaction with the current leadership's direction, leading to this organized split within the legislative assembly.

Mamata Banerjee now faces a dual challenge of managing a fractured party while attempting to maintain a working majority in the assembly. The recognition of the rebel leader by the Speaker complicates the government's ability to dismiss the faction as a mere fringe group.

The split within the Trinamool Congress creates a constitutional crisis in West Bengal. By securing the recognition of the Leader of the Opposition, the rebel faction gains official legitimacy, which is often a prerequisite for claiming the party's legal name and symbol in court. If the faction successfully argues it represents the 'real' party, Mamata Banerjee could lose the branding necessary to contest future elections.
