The TMC Tuesday likened its MLAs who have joined the BJP on Tuesday to "rats abandoning a ship sensing danger" and said people will give them a befitting reply.
Three West Bengal MLAs, including BJP leader Mukul Roy's son Subhrangshu Roy, and over 50 municipal councillors, most of them from the Trinamool Congress, joined the BJP on Tuesday.
TMC's Tusharkanti Bhattacharya and CPI(M)'s Debendra Nath Roy were other MLAs from the state who joined the saffron party, BJP leader Anil Baluni said.
Subhrangshu Roy was suspended by the TMC for his "anti-party" activities after the Lok Sabha election results were announced.
A senior TMC leader said, "We will expel them from the party. Subhrangshu is already under suspension. We are not bothered about such opportunists. People will give them a befitting reply."
