Chandrima Bhattacharya, the West Bengal state president of the Trinamool Congress (TMC), resigned from all party posts on July 4, 2026 [1].

The resignation marks a significant leadership blow to Chief Minister Mamata Banerjee as the party struggles to stabilize its organizational structure. This departure occurs during a period of heightened instability for the TMC in its primary stronghold.

Bhattacharya relinquished her role as the state president and all other organizational responsibilities she held within the party [2]. Reports indicate that her tenure in the state presidency lasted only weeks before her decision to step down [3].

The move follows a series of internal rifts and organizational challenges that have plagued the party [4]. These tensions escalated after the TMC suffered a recent defeat in the West Bengal assembly elections [4].

While some reports focused primarily on her role as the Bengal chief, other accounts confirmed the scope of her exit included every position she held within the party hierarchy [2]. The sudden nature of the resignation highlights the depth of the friction within the Mamata Banerjee faction [5].

The party has not yet named a successor for the state presidency. The departure of a high-ranking official so shortly after their appointment suggests a volatile climate within the party's state unit [3].

The resignation of a state president only weeks after taking office indicates a severe crisis of confidence and leadership stability within the Trinamool Congress. By exiting all party posts simultaneously, Bhattacharya's move suggests that the internal rifts following the assembly election defeat are systemic rather than personal. This leaves the party vulnerable as it attempts to reorganize its grassroots machinery in West Bengal.
