John Bercow has ruled out a “meaningful vote” on Boris Johnson’s Brexit deal as the Prime Minister fights to fend off new threats to his plans.

All eyes were on the Commons Speaker as he decided whether to allow the vote to take place on Monday.

Mr Johnson abandoned plans for a meaningful vote on Saturday when MPs backed a move forcing him to ask Brussels for a further delay.

But because the deal had been debated, Mr Bercow blocked a vote coming back so soon because of rules over the same matter being discussed twice.

It came after Chief Secretary to the Treasury Rishi Sunak denied that trying to bring the deal back for a vote was a bid to portray Parliament as being obstructive.

“It was an observation on the deal happening and I think what people need is a substantive vote,” he told BBC Radio 4’s Today programme.

“I think people are crying out to see that and they would find it odd if, because of some technical procedural device, we weren’t able to have that vote.”

Focus switches to the Government bringing its Withdrawal Agreement Bill (WAB) before MPs on Monday, with a vote on its second reading on Tuesday.

The WAB is the legally-binding treaty that must be passed for the UK to leave the bloc, while the Government must also win a meaningful vote.

Brexit Secretary Stephen Barclay called on MPs to “respect the referendum” by backing the Bill, warning them: “This is the chance to leave the EU with a deal on October 31.”

Ministers insist they could have sufficient support among MPs to get it passed so the UK can depart by the current October 31 deadline.

But, with no Commons majority, Mr Johnson faces a major battle to achieve his cast-iron pledge.
