Union Home Minister Amit Shah on Wednesday accused Bengal Chief Minister Mamata Banerjee  of compromising national security for the sake of vote-bank politics. He also added that she is "committing a sin" by allowing these intruders  to change the state's demography, reported news agency PTI.

While addressing a poll rally at Kanthi in East Midnapore district, Shah also said that the Trinamool Congress will "disintegrate", resulting in the "farewell" of the Mamata Banerjee government after the BJP wins 30 Lok Sabha seats in the state.
