"Sarma is nothing but an opportunist otherwise he would not have left Congress. Originally he was a leader of AASU (All Assam Students Union), then he had joined Congress and now in BJP," Gogoi said here, reacting to his once close confidante's decision to join BJP.
He said there were many leaders, including Sharad Pawar and P A Sangma, who had left the party but their departure had no impact on Congress.
Asked about reports that more than 40 MLAs support Sarma, Gogoi said if that was the picture, why no Congress MLA has announced his or her support to him till now.
On Sarma's statement that Congress would get hardly a dozen seats in the 126-member Assam assembly in next year's polls, Gogoi wondered whether Sarma had left the party fearing a defeat.
The Congress veteran dismissed Sarma's allegation that he was promoting his son Gaurav, an MP, saying if Sarma was afraid of Gaurav, what kind of politician was he.
