Kolkata: Throwing a challenge to West Bengal CM Mamata Banerjee on her home turf, BJP chief Amit Shah on Wednesday declared that the BJP will not rest till it conquers Bengal. He said the lotus will bloom in the Trinamul chief’s constituency Bhowanipore, too. “70 per cent is under the rule of the BJP. But until it comes to power in Bengal, the mission of Ebar Bangla (Now Bengal) will not be accomplished,” he said.
