Bengal Chief Minister Mamata Banerjee -- who declared yesterday that the INDIA bloc will not take a call on its Prime Ministerial candidate until after the Lok Sabha election -- took a 180-degree turn today by proposing Congress chief Mallikarjun Kharge's name for the position. Sources said Ms Banerjee made the proposal at the ongoing meet of the Opposition INDIA bloc. Mr Kharge being a prominent Dalit face in the Opposition, the plan got widespread approval.
