A group of 58 Trinamool Congress (TMC) MLAs has broken away from party leadership to support Ritabrata Banerjee as Leader of the Opposition.

This mass defection threatens the stability of the TMC government in West Bengal. The loss of a majority of its legislative members could shift the balance of power in the state assembly and weaken the position of Chief Minister Mamata Banerjee.

The rebel faction consists of 58 members [1] out of the 80 total TMC MLAs in the West Bengal Assembly [2]. This group is reportedly planning to join the National Democratic Alliance (NDA) coalition. The movement is being led by Ritabrata Banerjee, a first-time MLA who has managed to organize the dissent within a matter of weeks [1].

Internal discontent within the party grew following an electoral setback against the Bharatiya Janata Party (BJP) [1], [2]. This loss prompted the faction to seek a new alignment with the NDA to maintain political viability. The signatures of the 58 MLAs have already been submitted to formalize their support for Ritabrata Banerjee's leadership role.

Other figures mentioned in connection with the political shift include Kakoli Ghosh Dastidar and Sushmita Dev [1]. The movement represents a significant fracture in the party's ranks, a development that comes as the TMC attempts to recover from its recent losses at the polls.

The scale of the revolt is unprecedented for the party in the current assembly. By moving toward the NDA, the rebel MLAs are aligning themselves with the very coalition that contributed to the TMC's recent electoral decline [2].

The defection of 58 out of 80 MLAs effectively strips the Trinamool Congress of its legislative dominance in West Bengal. If these members successfully transition to the NDA, the state could face a constitutional crisis or a change in government, as the TMC would no longer hold a simple majority in the assembly.
