Seat-sharing talks between the Congress and the Trinamool soured last week after Mamata unilaterally announced her list, giving the Congress only 64 seats in the 294 constituency Assembly.
Soon after Congress President Sonia Gandhi flew in from abroad on Monday morning, she put the contentious seat-sharing issue on fast-track.
Sources had told The Indian Express that the Congress high command would abide by Trinamool chief Mamata Banerjees decision in order to avoid rampant division of the Left vote.
Congress has entered into a seat-sharing agreement with the Trinamool Congress for West Bengal Assembly polls. We expect that the alliance will give a chance to the people of Bengal to end misrule of the Left, AICC spokesman Shakeel Ahmed told reporters here.
