In 2014, Sarma led a dissident faction against Gogoi. It had become clear to him by then that he did not stand a chance to lead the party in the 2016 elections, as neither did Gogoi show any signs of giving up the reins, nor was Delhi in his favour. While Sonia Gandhi reportedly supported him after being briefed by Mallikarjun Kharge, Rahul Gandhi shot down the idea. What became a matter of concern for him further was Gogoi’s son Gaurav, now a Lok Sabha member, who joined the party in 2012. He was now certain Gaurav would get precedence over him. So finally, in July 2014, he resigned from the ministry. Next year, in August, he joined BJP. The party, which was desperately trying to find a foothold in the Northeast via Assam, lapped him up.
