"I have submitted my resignation to Speaker Shashank Sekhar Bhokta... I have informed him that I have quit Congress and joined Trinamool Congress," Dubey, who represented the House on Congress ticket, said.
Yesterday Assembly Speaker Shashank Sekhar Bhokta had said he was waiting for a genuine ground before considering anti-defection provisions against MLAs changing political parties ahead of the general elections.
Incidentally, Dubey said he would file nomination papers as Trinamool Congress candidate from Dhanbad.
