Vauxhall MP Kate Hoey insisted the UK must leave the bloc without a deal on Halloween unless the next prime minister can secure changes to the controversial Irish backstop. Brexiteers fear the measure, which is aimed at preventing a hard border in Ireland, could permanently trap Britain in the customs union and it has been the biggest obstacle to an agreement.
The Labour MP told Express.co.uk: “My bottom line is we must leave at the end of October and no delay is acceptable.
“Unless the new prime minister can get a change to the backstop we will leave on WTO terms.”
Ms Hoey added she is “relaxed” about a no-deal Brexit as the UK could go on to strike a Canada-style free trade agreement with the EU.
It comes as Boris Johnson and Jeremy Hunt are battling it out in the Tory leadership contest to replace Theresa May.
The pair have been taking part in hustings events across the country and it is up to Tory party members to pick the winner.
Voting is open and the party’s new leader will be announced on July 23.
Both candidates are aiming to strike a new divorce deal with the EU, after Mrs May’s agreement was rejected by MPs three times.
But they have pledged to quit the bloc without an agreement in place if necessary.
Frontrunner Mr Johnson has promised to leave on October 31 “do or die”, while the Foreign Secretary has admitted he would delay the exit date if a deal was within reach.
It comes after the original March date was pushed back.
Mr Johnson also dismissed warnings that Parliament will find a way to block a no-deal Brexit as a “red herring” and condemned the “defeatism and negativity” in Government about the prospect of leaving the EU at a hustings in Darlington yesterday.
