Union home minister Amit Shah slammed West Bengal Chief Minister Mamata Banerjee on Sunday ahead of polls in the state. Pointing to a spate of defections from the Trinamool Congress, Shah asserted that Banerjee will be left alone by the time assembly elections are held in the state. Polls to the 294-member Bengal assembly are expected to take place in April-May this year. Several TMC leaders including one of the founding members of the party, Bani Singha Ray, shifted allegiance to the BJP at the rally, which was attended by newly inducted former TMC minister Rajib Banerjee and many others. The TMC's slogan of "Maa, Mati, Manush" (mother, land and people) has been reduced to "dictatorship, tolabaji (extortion) and appeasement", Shah said while addressing the rally through video-conferencing in Howrah district.
