Days after West Bengal CM Mamata Banerjee reprimanded TMC leader Mahua Moitra, BJP MP Saumitra Khan claimed that Moitra won't stay in TMC for long. "Mahua Moitra will have to join the BJP after two years. We are waiting for that," Khan added. Khan further alleged that only Mamata's nephew Abhishek Banerjee's position "can remain intact forever" in the party.
