Theresa May has issued a last-ditch plea for MPs to back her Brexit deal, after Brussels chiefs issued a letter offering assurances that they do not want the controversial "backstop" to be permanent.
Speaking in a factory in Leave-voting Stoke-on-Trent, the British Prime Minister said the letter from European Council president Donald Tusk and European Commission president Jean-Claude Juncker made clear that the backstop was "not a threat or a trap".
And she also said she was committed to working with MPs from across the House to ensure that workers' rights and environmental standards were protected after Brexit.
Mrs May warned that MPs would be behaving with the "height of recklessness" if they rejected her Withdrawal Agreement in Tuesday's historic vote, when no alternative deal was on offer which was negotiable and respected the 2016 referendum result.
The Prime Minister said that the presidents' letter provided "valuable new clarifications and assurances" to address the concerns of MPs who fear the backstop, which is designed to prevent a hard border in Ireland, could become a permanent arrangement which the UK could leave only with approval from the EU.
She said the letter delivered:
"The letters published today have legal force and must be used to interpret the meaning of the Withdrawal Agreement, including in any future arbitration," said the Prime Minister
They make absolutely clear the backstop is not a threat or a trap.
"I fully understand that the new legal and political assurances which are contained in the letters from Donald Tusk and Jean-Claude Juncker do not go as far as some MPs would like.
"But I am convinced that MPs now have the clearest assurances that this is the best deal possible and that it is worthy of their support."
In their letter, Mr Tusk and Mr Juncker stressed they were "not in a position" to rewrite or amend the Withdrawal Agreement secured by Mrs May last year.
But they assured the PM that the EU "does not wish to see the backstop enter into force", as it would represent a "sub-optimal trading arrangement for both sides".
The EU wants to ensure it would "only be in place for as long as strictly necessary".
The EU presidents stated: "Were the backstop to enter into force in whole or in part, it is intended to apply only temporarily, unless and until it is superseded by a subsequent agreement."
Warning that failure to deliver Brexit would do "catastrophic harm" to trust in the political process, Mrs May said: "There are some in Westminster who would wish to delay or even stop Brexit and who will use every device available to them to do so.
"I ask them to consider the consequences of their actions on the faith of the British people in our democracy ... People's faith in the democratic process and their politicians would suffer catastrophic harm.
We all have a duty to implement the result of the referendum.
With expectations high at Westminster that the Prime Minister is heading for a crushing defeat in Tuesday's crucial vote, Mrs May issued a plea to MPs concerned about the danger of a no-deal Brexit to back her.
"The only ways to guarantee we do not leave without a deal are: to abandon Brexit, betraying the vote of the British people; or to leave with a deal, and the only deal on the table is the one MPs will vote on tomorrow night," she said.
"You can take no-deal off the table by voting for that deal. And if no-deal is as bad as you believe it is, it would be the height of recklessness to do anything else."
Letter from EU offers assurance that Brexit backstop will only be temporary
European Union chiefs have sent Theresa May a letter confirming that Brussels does not want the so-called “backstop” to remain in place permanently following Brexit.
But European Council president Donald Tusk and European Commission president Jean-Claude Juncker stressed they were “not in a position” to rewrite or amend the Withdrawal Agreement secured by Mrs May last year.
The letter comes ahead of Tuesday’s vote on the agreement in the House of Commons as the Prime Minister makes an eleventh-hour bid to secure MPs’ support for her deal.
Many Conservative MPs are threatening to rebel on Tuesday because of their concerns that the UK could be permanently trapped in the backstop arrangements – designed to avoid a hard border in Ireland and requiring compliance with some EU rules – and be unable to pull out without approval from Brussels.
In letter to Mr Tusk and Mr Juncker requesting additional assurances, Mrs May wrote: “The clarifications and undertakings proposed in this letter are consistent with the letter and spirit of the deal we have reached, but would be further reassurance that the fears that some hold on both sides are misplaced.”
In their response, the EU presidents stated that they regard the Withdrawal Agreement as a “fair compromise” which would limit “the negative consequences of Brexit”.
The European Union “does not wish to see the backstop enter into force”, as it would represent a “sub-optimal trading arrangement for both sides”, they said. The EU wants to ensure it would “only be in place for as long as strictly necessary”.
The Withdrawal Agreement makes clear that that backstop comes into effect only if no broader deal on future relations has been reached by the end of the Brexit transition period in December 2020 – or after a potential extension of up to two years if that is triggered.

The EU presidents stated: “Were the backstop to enter into force in whole or in part, it is intended to apply only temporarily, unless and until it is superseded by a subsequent agreement.”
At a European Council summit on December 13, leaders of the remaining 27 member states agreed a “firm commitment” to work speedily to deliver an agreement which meant that the backstop would not be needed, said the letter.
They have agreed that, if needed, it should apply only “temporarily” and the EU would “use its best endeavours to negotiate and conclude expeditiously a subsequent agreement that would replace the backstop”.
The letter said that the commission was “committed to providing the necessary political impetus and resources” to ensure that a future relationship agreement is drawn up as quickly as possible”.
The letter confirmed that both Mr Tusk and Mr Juncker were ready to sign the Withdrawal Agreement as soon as the so-called “meaningful vote” is passed by the UK Parliament, allowing preparations for a future partnership to begin “immediately thereafter”.
