A day after his wife and two sons were summoned for questioning by the central agency Enforcement Directorate in a corruption-linked case, Trinamool Congress MLA Madan Mitra on Wednesday shifted allegiance from Mamata Banerjee's camp to the rebel faction led by Ritabrata Banerjee. He said he had “only changed my room in assembly”.Madan Mitra with Trinamool Congress (TMC) rebel faction leader Ritabrata Banerjee after saying he had resigned from posts in the TMC led by Mamata Banerjee. (Video grab: PTI)He said he wanted Mamata's nephew and the party's national general secretary Abhishek Banerjee — who has been blamed by many rebels for the TMC split — to “step aside for six months” but quit when that demand was not accepted.“I told ]Abhishek], let us build the party, and then you can come back and take your seat, but he refused. He said, 'I won't leave the party.' The party is sinking; the boat has gone under. People are dying. Yet, the party decided or rather it was forced to accept that everyone else could die, but Abhishek had to be saved. It is deeply saddening,” Mitra said at a press conference, seated next to Ritabrata, who has most of the 80 TMC MLAs with him and is the Leader of Opposition in the assembly at present.The split in Mamata's party has only grown since the BJP unseated her and the TMC regime after 15 years in the elections results in May. With most of the MLAs and MPs having either switched to the rebel faction or technically “merged” into a small party from Tripura, the issue of who has the original TMC is being contested before the Election Commission.Mitra further said, “The party belongs to everyone, yet it seems to have been reduced to serving only Abhishek. I earnestly request Mamata ji to come, let us view this as a marathon. We will surely cross paths along the way. Let us see which horse surges ahead. I have resigned from all the positions. Though I remain an MLA. I have left everything associated with Trinamool. That means I am no longer a Trinamool MLA in the functional sense,” Mitra said.Mamata, Abhishek and the MPs who are still with them, such as Mahua Moitra, have alleged that the “rebellion” is because of inducements, greed, or fear of the BJP and the central agencies under PM Narendra Modi's government at the Centre.
