Rishi Sunak delivered a scathing verdict on a Tory campaign to keep Boris Johnson in Downing Street - after he was confronted by an angry party member accusing him of disloyalty.
The former Chancellor, whose departure marked the start of a mass walkout which ultimately brought down Mr Johnson, said the PM had lost the support of his own MPs.
More than 14,000 Tories have backed a campaign for the outgoing leader to be included on the ballot in the leadership contest.
