West Bengal CM Mamata Banerjee on Thursday pulled up Krishnanagar MP Mahua Moitra during a meeting, saying infighting within TMC won't be tolerated. "Mahua, I want to give a clear message here...When there is an election, the party will decide who will contest," Banerjee added. Supporting Mahua, BJP's Suvendu Adhikari said the 'insult' by Banerjee drove him to leave TMC.
