Game for Prez poll not over yet: Mamata

West Bengal chief minister and a key ally in the UPA government Mamata Banerjee has said that the game for the Presidential poll is 'not over yet'. UPA Chairperson Sonia Gandhi named Mukherjee as the government's nominee for the post of the president while urging the political fraternity to back him. This came as a big setback for Banerjee who had recently given forth the names of three candidates of her choice along with Samajwadi Party (SP) leader Mulayam Singh Yadav.
