The Rushcliffe MP said: “If it’s heading for a no deal simply because the Government can’t go round doing anything then, yes, I think I would.
“I am a life-long Conservative, that means I am pro-business, I am in favour of free markets, I am in favour of free trade and I think all of those should be combined with a strong social conscience because I am a one nation Conservative.”
Mr Clarke added: “It might trigger an election, it might trigger a change of Government without an election under the law we now have.”
Former Foreign Secretary Boris Johnson, who has emerged as the most-supported MP to succeed Mrs May in Number 10 after four rounds of ballots, insisted he would ensure the UK leaves the EU “with or without a deal” on October 31.
Despite taking a more pondered approach to Brexit, Mr Johnson’s opponent Jeremy Hunt also admitted he would be willing to greenlight a no deal “in extremis” if no alternative solution is found to the controversial withdrawal deal the Commons rejected three times.
