Any attempt by the next prime minister to suspend Parliament to force through a no-deal Brexit is likely to end up in the Supreme Court, a Tory MP has said.
Sir Oliver Letwin told the BBC it was not clear whether MPs had the numbers to stop a no-deal Brexit themselves.
But if the government tried to get its way by by-passing Parliament, he said it would become a "legal question".
Campaigners say they will challenge any "prorogation" of Parliament to allow Brexit on 31 October without a deal.
