Maharashtra leader Sharad Pawar today declined Mamata Banerjee's offer to be the opposition's Presidential candidate, saying he "still has an active political innings to play". Sharad Pawar, 81, had earlier shut down speculation on the top post at a meeting with his party leaders, who revealed that the former Union Minister was reluctant to fight "a losing battle". At a meeting of opposition parties called by Mamata Banerjee, he made it official.
