Senior Trinamool Congress leader and former West Bengal minister Madan Mitra has resigned from all party posts and joined the rebel TMC faction led by Ritabrata Banerjee, dealing a fresh setback to Mamata Banerjee's party. After switching camps, Mitra launched a sharp attack on Abhishek Banerjee, alleging that the party had become centered around him and claiming he had urged Abhishek to step aside to help rebuild the organisation. The move comes amid growing dissent within the TMC following its recent electoral defeat.
