Former West Bengal Finance Minister Chandrima Bhattacharya, a close ally of Trinamool Congress (TMC) leader Mamata Banerjee, has resigned from all party positions following months of internal strife within the ruling party.

The resignation comes after the TMC suffered a significant defeat in the state Assembly elections to the BJP, triggering widespread dissent among MLAs.

Bhattacharya joined a meeting with rebel TMC leaders, including Leader of Opposition Ritabrata Banerjee, signaling potential alignment with the opposition faction.She accused the party leadership of excluding her from critical decisions, such as budget preparation, during its time in power.The TMC's internal divisions have escalated since May, with over 60 MLAs rebelling to support Banerjee as Opposition leader.

Meanwhile, Mamata Banerjee condemned the rebels as 'traitors' and vowed to continue leading the party, emphasizing her commitment to TMC workers over leaders.The political turmoil highlights deepening fractures within the TMC, raising questions about its stability and future governance in West Bengal.
