More than 100 legislators of Mamata Banerjee's Trinamool Congress are in touch with the BJP, party leader Mukul Roy claimed today as three more lawmakers joined the BJP on the second consecutive day. The BJP has promised a seven-round exodus of lawmakers from Ms Banerjee's party to match with the seven-phase election. The exodus comes weeks after Prime Minister Narendra Modi told the Bengal Chief Minister that 40 legislators from her party were in contact with the BJP and would change camp after the national elections.
