Culture Secretary Nadine Dorries has blamed Rishi Sunak for the "ruthless coup" which ousted Boris Johnson from No10.
Ms Dorries, a staunch Johnson loyalist, renewed her attacks on the Tory leadership hopeful, who she named as a ringleader in removing the Prime Minister from Downing Street.
In a series of outspoken interviews - one of which was interrupted by someone shouting at a cameraman - Ms Dorries tore into Mr Sunak and said she was "bitterly disappointed" by Mr Johnson's resignation.
