Sir Bill Cash has said Cabinet members who had spoken out against leaving the EU should be "sacked".
Appearing on the breakfast show, the Conservative MP for Stone said the "threats" made by some to defy Theresa May if a no-deal Brexit became likely should have led to expulsion from their roles.
"I do think that the behaviour of some of the members of the Cabinet, the threats by Amber Rudd and the rest of them, should have led to them being sacked," Sir Bill told talkRADIO's Julia Hartley-Brewer.

"The fact is that the people in the House of Commons who are not remainers, but reversers, want to rejoin the EU, which includes people like Dominic Grieve who are absolutely, completely defying the result of the referendum."
He added that it was "appalling to see" other MPs coming out against Brexit, despite supporting it in previous votes and the Conservative manifesto.

"The referendum itself was conducted in a lawful manner. They voted for the Withdrawal Act, and voted for the notification Withdrawal Act, not in small numbers," he recounted.
"They voted for the referendum and their manifestos all said they would respect the referendum."
He added: "What is appalling to see is the way in which people are reversing their recent votes for no reason at all."
