Theresa May faces confidence vote in her Government soon, Jeremy Corbyn warns

Britain's Prime Minister Theresa May speaks outside 10 Downing Street after a confidence vote by Conservative Party Members of Parliament, in London Britain

Ministers have warned the United Kingdom faces Brexit "paralysis" if this happens.

During a visit to Romania on Friday, Jean-Claude Juncker, president of the European Commission, said that despite Prime Minister Theresa May's struggles to get the deal through the United Kingdom parliament, he continues to hope she can secure backing for it in Tuesday's vote.

While Grayling stopped short of predicting riots on the street if Brexit was weakened or reversed, he painted a picture of a "less tolerant society" and a "more nationalistic nation", as indicated by the incident with pro-Remain MP Anna Soubry.

The Foreign Secretary appealed to MPs to come together behind a Withdrawal Agreement which is "not perfect" but "broadly delivers Brexit". "It would be a catastrophe", Juncker said.

He told the BBC: "We will table a motion of no confidence in the government at a time of our choosing, but it's going to be soon, don't worry about it".

He said if it is defeated, Britain should continue to press the European Union for a deal that "respects the referendum but if Brussels' "intransigence" persists "we must be willing to leave the European Union at the end of March on World Trade Organisation terms".

Jeremy Corbyn has dashed hopes he could back a so-called "People's Vote" by saying he wants a renegotiated Brexit deal.

"I think it's now looking much less likely that parliament would allow a no-deal outcome", he told the BBC.

"Mrs May said: "You, the British people, voted to leave".

Corbyn confirmed that he would not consider supporting the government in the meaningful vote on Tuesday, despite Theresa May's last-ditch attempts to garner support for her deal from members on the opposition benches.

Labour peer Lord Andrew Adonis, who is a prominent Remainer, slammed Grayling and in a tweet wrote: "At the end of Brexit there should a one clause bill banning Grayling from holding any further public office ... unless of course it's overturned by a people's vote".

"I think that is something that we would regret for many, many generations".

The speaker has been "religiously fair", says Corbyn.

Insisting that he had not given up hope of victory in next week's vote, he said: "What is important is for MPs on all sides, Brexiters and Remainers, whatever our disagreements, to say "We are democrats and the most important thing now is to make sure that we really do deliver Brexit".

And the prime minister made efforts to reach out to Labour and the unions in an 11th-hour bid to salvage a vote which she is expected to lose by a wide margin.

The PM has also faced further opposition to her deal from former Brexit secretary Dominic Raab, who used an article in the Sunday Telegraph to urge MPs to vote down Mrs May's "bad" deal and send a message to Brussels that the United Kingdom "will not be bullied". "I just can't see how it happens with that configuration of Parliament".
