West Bengal Chief Minister Mamata Banerjee on Saturday hit out at Prime Minister Narendra Modi for his visit to Bangladesh, accusing him of trying to influence voters in West Bengal where polling began for the eight-phase assembly election in the morning. "Elections are underway here and he (PM) goes to Bangladesh and lectures on Bengal. It is a total violation of code of conduct of the election," Ms Banerjee said at a campaign event in Kharagpur according to news agency ANI.
