The Bharatiya Janata Party (BJP) chief Amit Shah has sounded the poll bugle for the Lok Sabha elections by holding a rally in West Bengal on Tuesday. Amit Shah is scheduled to hold multiple rallies in parts of Bengal staring from Malda district. Malda, a border district in north Bengal, was a Congress stronghold for decades with its politics being dominated by party veteran A B A Ghani Khan Chowdhury and his family.
