One of the rebel lawmakers of the Congress in Karnataka, who on Saturday raised hopes for the troubled Congress-Janata Dal Secular coalition by hinting he may take back his resignation, was today seen in Mumbai, creating a buzz on his next move. Congress legislator MTB Nagaraj, one of the 16 coalition legislators who have resigned from the state assembly over the past week, had agreed to come back to the coalition fold after being coaxed by Congress leader Siddaramaiah and Chief Minister HD Kumaraswamy. He later set a condition for his return; he said another rebel, Sudhakar Rao, would have to withdraw his resignation as well.
