Congress on Tuesday expelled its West Bengal unit General Secretary Binoy Tamang for six years for "anti-party activities", after he extended his support to BJP's Darjeeling candidate Raju Bista. "It doesn't matter...My expulsion from the Congress is a...defeat for the grand old party," Tamang said. "How many people will Congress expel for supporting PM Narendra Modi?" said BJP's Amit Malviya.
