Mamata Banerjee, leader of the Trinamool Congress (TMC), has dissolved all party committees and frontal organisations in West Bengal following a deepening internal rift.

This move signals a critical instability within the ruling party's structure. The scale of the rebellion threatens the government's legislative majority and the long-term authority of the party leadership in the state.

The crisis follows a recent assembly election loss that intensified discord among party members. Legislators have rebelled against the leadership of Banerjee and her nephew, Abhishek Banerjee [1, 2]. This internal friction has reached a point where approximately 60 of the party's 80 legislators are now aligned with the rebel faction [1].

In a significant shift in legislative dynamics, the party has recognized expelled MLA Ritabrata Banerjee, who leads the rebel group, as the opposition leader in the state assembly [1, 2]. This recognition formally acknowledges the split between the loyalists, and the dissidents.

While the dissolution of committees is intended to reorganize the party, the loss of support from the majority of its legislators creates a precarious political environment. The rebellion reflects a broader dissatisfaction with the current leadership's direction after the electoral setback [1, 2].

Party loyalists have continued to attend review meetings with the West Bengal Chief Minister, but the numeric imbalance among legislators remains a primary challenge for the administration [2].

The dissolution of party organs combined with the recognition of a rebel leader as the official opposition suggests that the TMC is no longer functioning as a monolithic entity. With 75% of its legislators in rebellion, the party faces a potential collapse of its legislative mandate, which may lead to a realignment of power in West Bengal or a forced restructuring of the party's internal hierarchy.
