Big controversy involving TMC's firebrand MP Mahua Moitra has erupted after BJP MP and member of Parliament's Standing Committee on IT accused her of calling him a 'Bihari Gunda'. Dubey said that Mahua made derogatory remarks against him during the meeting of IT panel on Wednesday. However, Mahua has said that she was amused at the allegation, claiming that the meeting of the IT never took place and that Dubey was not even present in front of her.
