Dominic Raab said MPs who have tried to “derail” Brexit will ultimately be judged by their constituents at an election.
The Foreign Secretary told talkRADIO’s Julia Hartley-Brewer staunch remainers would face a "reckoning" when forced to defend their seats.
“There will be ultimately a reckoning with the voters and everyone will have to be accountable for the decisions they make," he said.
The cabinet minister added that he would ignore the “froth and frenzy” from the Liberal Democrats, who have pledged to revoke Article 50 if elected.
“They [the Lib Dems] were the original ones championing a referendum back in the day. Now having had it they want to cancel the result,” he said.
“Not only are they airbrushing the referendum, if any other tin pot banana republic did this in any other part of the world the Lib Dems would be calling it out immediately.”
Mr Raab said the Prime Minister was close to a deal, as he heads for talks with European Council president Jean-Claude Juncker in Luxembourg today.
He supported Boris Johnson’s pledge to leave the EU on October 31, despite a newly-passed law that required the Prime Minister to ask for an extension if a deal cannot be found by mid-October.
“The outlines of this deal I think are pretty clear now. We would remove the anti-democratic backstop and we’d be clear that the future relationship would transition to a best-in-class free trade agreement,” he said.
“This ultimately comes back to whether the EU wants to meet us halfway, do a deal that works for all sides, and if not the Prime Minister’s been clear we leave at the end of October.”
