In yet another significant setback to the ruling Trinamool Congress (TMC) in West Bengal, Barrackpore MLA Shilbhadra Dutta resigned from key post of the party on Friday. This is the third major exit from the party in two days. Earlier, senior party leader and former minister Suvendu Adhikari resigned from the party and joined BJP. Baffled by a series of resignations that have hit the party ahead of the Assembly elections scheduled for next year, Chief Minister Mamata Banerjee had reportedly called for an emergency meeting on Friday. Party sources, however, downplayed the meeting and said it was a ‘regular’ affair. Besides, Adhikari, Chairman of South Bengal State Transport Corporation (SBSTC) Colonel (R) Diptangshu Chaudhury also tendered his resignation to Banerjee on Thursday. “I do hereby tender my resignation from my office as Chairman South Bengal State Transport Corporation (SBSTC) and also as Advisor, Monitoring Cell on Programme Implementation of Government Welfare Services in Chief Minister’s Office (Grievance & Monitoring Cell). I am also informing the same by email to His Excellency, Governor of West Bengal, being the constitutional head of the state. I convey my gratitude to you for giving me an opportunity to serve the people of my state which I did with utmost sincerity, dedication and responsibility,” Chaudhury said in his resignation letter.
