Trinamool Congress chief Mamata Banerjee has told district leaders of the Trinamool Congress to be prepared to field candidates in all the three Lok Sabha seats in Murshidabad district, sources said. Ms Banerjee's instruction to her party was seen as posturing to its INDIA bloc partner Congress, headed by Mallikarjun Kharge. The Congress is yet to respond on seat-sharing talks with the Trinamool for Murshidabad, which has three Lok Sabha seats, two of them held by Ms Banerjee's party and one by the Congress.
