Trinamool Congress (TMC) MP Mahua Moitra on Wednesday criticised senior leader Madan Mitra after he joined the rebel faction led by Ritabrata Banerjee. Speaking in Kolkata, Moitra alleged that Mitra's decision was linked to the Enforcement Directorate (ED) summons issued to his family members in connection with a money-laundering investigation related to an alleged municipal recruitment scam in West Bengal.
