Peter Bone has urged Theresa May to embrace a no-deal Brexit and "honour" the result of the EU referendum.
The Conservative MP appeared on the breakfast show in the wake of last night's second round of "indicative votes", in which MPs rejected all four alternatives to Theresa May's Brexit deal.
Following the failed vote, Mr Bone said the Brexit process was now "entirely in the Prime Minister's hands".
"She can go over there [Brussels] and say 'Look, we've tried everything, there is no other way than coming out on a no-deal basis'. And that's exactly what she should do," he told talkRADIO's Julia Hartley-Brewer.
"It's as simple as that. Parliament can't stop her doing that, she just goes over there and says that is what has got to happen."
He added: "I do not understand why some of our politicians are trying to avoid what the British people wanted."
