Krishna Chakraborty, a close aide to West Bengal Chief Minister Mamata Banerjee, resigned as mayor of the Bidhannagar Municipal Corporation on June 4, 2026 [1].
The resignation signals a deepening instability within the Trinamool Congress (TMC). As a high-ranking official and trusted associate of the chief minister, Chakraborty's departure suggests a fracture in the party's internal leadership structure during a period of heightened political volatility.
This move is part of a series of setbacks and an internal party crisis currently affecting the TMC [1], [2]. The political landscape in West Bengal has become increasingly unstable as the ruling party faces challenges from within its own ranks, a situation that complicates the administration's governance of the state.
The crisis extends beyond municipal leadership. Reports indicate that 19 members of parliament have indicated they have joined the Bharatiya Janata Party (BJP) [3]. This mass defection of lawmakers represents a significant loss of legislative power for the TMC and strengthens the opposition's foothold in the region.
While the specific motivations for Chakraborty's personal resignation were not detailed in the official announcement, the timing coincides with these broader party shifts [1]. The loss of a key ally in Bidhannagar, combined with the departure of nearly 20 lawmakers, places significant pressure on the leadership of Mamata Banerjee.
Local officials have not yet named a successor for the mayoral post. The party continues to navigate the fallout from these exits as it attempts to stabilize its organizational structure in West Bengal [2].
“Krishna Chakraborty resigned as mayor of the Bidhannagar Municipal Corporation on June 4, 2026.”
The simultaneous loss of a key municipal leader and a large bloc of parliamentarians suggests a systemic collapse of loyalty within the Trinamool Congress. By losing 19 MPs to the BJP, the party faces a diminished mandate and a weakened bargaining position in national and state politics, potentially shifting the balance of power in West Bengal toward the opposition.
