Ritabrata Banerjee, an expelled Trinamool Congress (TMC) leader, was approved as the Leader of Opposition in the West Bengal Legislative Assembly on June 3, 2026 [1].
The appointment signals a significant fracture within the ruling party in Kolkata. By recognizing an expelled member as the official opposition leader, the assembly acknowledges a formal split that challenges the authority of TMC chief Mamata Banerjee.
Speaker Rathindra Bose approved the appointment after Banerjee arrived at the assembly to submit signatures from supporting legislators [2]. The move follows a period of internal rift that led to Banerjee's expulsion from the party [3].
There are varying reports on the scale of the defection. Some reports indicate that Banerjee claimed support from more than 50 MLAs [4], while other accounts suggest the TMC legislature party consists of a team of 58 MLAs who won on the party symbol [5].
Despite his new role as the primary antagonist in the assembly, Banerjee has maintained a complex relationship with the party's founder. He said that Mamata Banerjee remains their chief [6]. Other reports indicate he wants Mamata Banerjee to serve as a chief advisor [7].
The development marks a sudden shift in the legislative landscape of West Bengal. The recognition of the LoP role typically requires a specific threshold of seats, and the Speaker's approval suggests that the number of MLAs siding with Banerjee meets the necessary legal or procedural requirements [2].
“Ritabrata Banerjee was formally recognized as the Leader of Opposition in the West Bengal Legislative Assembly.”
The appointment of an expelled member as Leader of the Opposition suggests a systemic collapse of party discipline within the Trinamool Congress. Because the LoP role is a statutory position, the Speaker's approval validates that a substantial bloc of legislators has broken away from the central leadership. This creates a precarious legislative environment where the ruling party may face internal challenges to its majority and governance in West Bengal.
