TMC MLA Madan Mitra, seen as Trinamool Congress matriarch Mamata Banerjee's aide for years, switched sides on Wednesday, joining the party's rebel camp. This comes a day after Mitra's wife and two sons were summoned by ED in a corruption case. Mitra blamed Mamata's nephew Abhishek Banerjee, saying everyone is being "left to die" to save him.
