Sarma, a dissident Congress leader till he joined the BJP, told a press conference that he had filed the defamation case against Gogoi in the civil court, Kamrup, for making "false allegations" against him.
"Recently Chief Minister Gogoi has been saying things against me. Sometimes he says I am an accused in the Saradha ponzi case and Louis Berger case. He has also said that there are criminal cases against me," the former minister said.
