Jeremy Hunt has warned of "Brexit paralysis" if MPs voted down Theresa May's withdrawal plan next week, potentially meaning the UK would not leave the European Union at all.

And in a significant signal, the Foreign Secretary suggested, following this week’s procedural row involving the Commons Speaker, that Parliament would not allow a no-deal outcome to happen.

In an interview with BBC Radio 4’s Today programme, Mr Hunt warned that failure to deliver Brexit would be "incredibly damaging" for the UK and something the country would regret for "many, many generations".

He appealed to MPs who have spent months fighting for their "number one top favourite outcome" to come together behind a Withdrawal Agreement which was "not perfect" but "broadly delivers Brexit".

Mr Hunt suggested that legally binding assurances from Brussels over the deal's controversial backstop arrangements should be enough to allay the fears of many MPs over the long-term impact of the Agreement.

Meanwhile, Work and Pensions Secretary Amber Rudd said she was "committed" to ensuring that the UK did not leave without a deal.

And three times she declined to say whether she would remain a member of the Government if it opted for a no-deal Brexit.

The Cabinet ministers were speaking as MPs prepared for the third day of debate in the House of Commons ahead of next Tuesday's crunch vote, with Home Secretary Sajid Javid opening proceedings which are expected to be dominated by the issue of migration.

In a significant shift of tone apparently designed to win over hardline Brexiteers who have set their faces against Mrs May's deal, Mr Hunt warned that defeat next week would not necessarily provide MPs with the opportunity to choose their preferred version of Brexit.

Warning that there may be no consensus in the Commons around any possible outcome, the Foreign Secretary told Today: "If this deal is rejected, ultimately what we may end up with is not a different type of Brexit but Brexit paralysis.
"And Brexit paralysis ultimately could lead to no Brexit.

"I'm saying this would be (an) incredibly damaging breach of trust and it would also be very bad for Britain's reputation abroad, having decided to leave the EU, if we in the end for whatever reasons found we weren't able to do it."

Mr Hunt warned: "If we were, as a political class, not to deliver Brexit, that would be a fundamental breach of trust between the people and the politicians. That is something that we would regret for many, many generations."

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.'"

The Foreign Secretary also warned Eurosceptics that they might not be able to rely on the clock ticking down to the default option of a no-deal Brexit on March 29 if Mrs May's deal were voted down.

He explained it was not possible for the minority Tory administration to control what happened in Parliament, noting how John Bercow, the Speaker, had shown that he was "willing to frustrate the Government at every opportunity".

Mr Hunt said: "It's now looking much less likely that Parliament would allow a no-deal outcome anyway. We have seen from this week that Parliament has the ability to assert itself and to shape outcomes.

"Parliament is very committed to try to stop no-deal but we have to recognise that there is a deal on the table, it does broadly deliver the Brexit people voted for, and if we don't find a way to get this through, we are taking some very big risks."

Labour’s David Lammy for the People’s Vote campaign, said: “Jeremy Hunt has confirmed publicly what more and more of his colleagues are saying in private: that if MPs can’t agree on Theresa May’s deal next week, the only way forward is to give the public the final say on Brexit through a People’s Vote.

“The idea that if MPs vote down the deal, we head to no-deal has always been a false threat and the Foreign Secretary has now effectively admitted it.”

The London MP added: “There is no Brexit deal that fulfils all the promises made in the last referendum or one as good as the deal we’ve already got inside the EU. Instead of embarking on another fruitless effort of renegotiation, it is time to hand this crucial decision back to the people.”

Mrs May was boosted on Thursday by two Tory backbenchers - her former policy adviser George Freeman, and Trudy Harrison - indicating they would back her deal as well as by a call from Japanese PM Shinzo Abe for the UK to avoid a no-deal.

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.

Asked whether she agreed with Mr Hunt that the UK could thrive after a no-deal Brexit, Ms Rudd told Today: "This is a strong and great country, we will find a way to succeed but I do not think that no-deal would be good for this country and I'm committed to making sure we find an alternative."

The Secretary of State said it was "right" for the Government to make preparations for a no-deal Brexit, comparing it to wearing a seatbelt when driving a fast car.

But she stressed: "I intend to work with colleagues to make sure we avoid it. I am committed to getting the best outcome for this country, which is supporting the Prime Minister's deal."

Pressed for a third time by interviewer Justin Webb on whether she would quit if Mrs May went for the no-deal option, Ms Rudd cut him short by saying: "Thank you very much, Justin."
