TMC MP Koel Mallick resigns from the Rajya Sabha on Thursday, according to multiple reports. Her resignation letter states that she “resign[s] from the membership of Rajya Sabha” and requests that it be accepted with immediate effect. One outlet reports that she meets the Vice President and Rajya Sabha Chairman C. P. Radhakrishnan to submit the resignation. The resignation comes amid a broader political reshuffle within the Trinamool Congress. Reports link the move to recent departures by other TMC figures, including Madan Mitra, who is said to have joined a rebel faction led by Ritabrata Banerjee and resigned from posts in the party. Other former TMC Rajya Sabha members—Sushmita Dev, Sukhendu Sekhar Ray, and Prakash Chik Baraik—also join the BJP and file nomination papers, with the decision described as part of the BJP’s response to the vacated seats. The Election Commission’s announcement of bypolls for Rajya Sabha seats vacated by these members is cited as the immediate context for speculation about their political return. Overall, sources agree Mallick’s resignation is formal and immediate, occurring during ongoing party realignments.
