Sir Nicholas Soames tells BBC Newsnight's political editor, Nicholas Watts, that he and most of the Tory rebels will back the deal.

The DUP's Brexit spokesman Sammy Wilson has said the party will not support Boris Johnson's deal over fears it will harm Northern Ireland.

Writing in the Daily Telegraph, external, Mr Wilson said his party has "sought to be flexible and stretched ourselves" to help the prime minister achieve a "fair deal with the EU".

But Mr Wilson said the deal risks being "economically damaging" to Northern Ireland, which he said is "a part of the UK which already faces economic disadvantages".

He said that the DUP does not want to "thwart" Brexit, but "we will not support a deal which is detrimental to Northern Ireland".

Labour's Peter Kyle, who backs a further referendum, says he is “raring to go” when it comes to voting for the proposal in the Commons.

He says MPs in his camp "might" push for such an outcome when MPs vote on the PM's Brexit deal on Saturday, but will not confirm whether this will happen or not.

However, he says speculation that such as move has already been ruled out are "premature".

“It still might come up on Saturday," he adds.

Meanwhile, the final conclusions, external from the European leaders' summit have been published.

It confirms EU leaders have agreed to the revised Brexit deal negotiated by UK and EU officials.

The document also calls on the European Parliament - which as well as the Commons will need to ratify the deal - to take steps to ensure it can come into force on 1 November.

There is no mention of ruling out a further Brexit delay if the deal is voted down by MPs on Saturday.

Earlier Jean-Claude Juncker, who as president of the European Commission would not get a formal say on any extension, said he was against such an outcome.

The PM has agreed a deal with the EU, and now the next step is for the UK Parliament to approve it.

Remember, MPs in Parliament voted down Theresa May's deal three times, meaning the agreement couldn't become law and so the UK did not leave with a deal.

On Saturday, MPs will vote on the new Brexit deal. The special Saturday sitting is extremely rare, having only ever happened four times since 1939.

As things stand, though, Northern Ireland's DUP - which has 10 MPs - does not support the deal so the vote could be close.

Our flowchart explains the different scenarios.

A group of cross-party MPs has written, external to Chancellor Sajid Javid asking him to release economic impact assessments for the new deal ahead of Saturday's vote.

The letter was written by Plaid Cymru MP Liz Saville Roberts, and includes signatures from former Conservatives Dominic Grieve and David Gauke, and Liberal Democrat leader Jo Swinson.

It points to government impact assessments published in November 2018 which "showed a significant negative impact on the UK economy in all scenarios".

"I am sure you would not wish to deprive Parliament, as representatives of the people of the UK, less information than that provided by previous Governments," it reads.

"Of course, if you are confident in your deal, you will have nothing to conceal from either Parliament or the public."

He did it. They did it.

Boris Johnson and his team, who beat the odds in 2016, have overturned the conventional wisdom again.

The EU said they would not budge; their former Tory colleagues and the opposition colleagues said it was all a sham.

But after a breakneck set of negotiations, a deal's been struck and the rest of the continent gave way on the controversial backstop, the feature of the former agreement that did for Theresa May.

However, Mr Johnson had to cede some ground too, accepting that Northern Ireland will be treated differently to the rest of the UK and follow some EU rules and regulations, perhaps for good.

Asked by David Dimbleby how his deal will help to heal the deep divisions over Brexit in the UK, Mr Johnson replies, saying it's an "Important question".

"I do think that the answer is that it will because what it will enable us to do, is to get the process of extraction behind us and enable us to come together and focus on building a new partnership across the Channel.

"Not just our friends in Brussels, but in every other European capital."

Asked whether he will suspend any Tory MPs who don't vote for his deal, he says he is not going to talk about whipping.

But he adds that he thinks there is a "very good case for voting for this deal".

"It's a big and important vote and we will be making further announcements about it in due course," he adds.

Mr Johnson says Brexit has been long, painful and divisive.

Asked by the BBC's Laura Kuenssberg why he is so confident that MPs will approve the new deal, Mr Johnson replies "there is a very good case for MPs to express the democratic will of the people... and to get Brexit done".

"I don't think there is any case for delay," he adds.

Boris Johnson has started his press conference by thanking his colleagues and saying the deal is not only "great" for the UK, but also for the EU.

"We in the UK can come out of the EU as one United Kingdom," he says.

Mr Johnson adds that he is confident that his colleagues in Parliament will want to vote for it, after they study the text.

Speaking to reporters, German Chancellor Angela Merkel says the EU decided not to set pre-conditions ahead of the vote on Saturday when MPs will decide whether to back the new Brexit deal.

The EU did not negotiate on the basis that the deal would be rejected, and Boris Johnson said he was confident the agreement would be approved, she adds.

She adds that the new agreement is more specific than the deal negotiated by Theresa May about the future relationship the UK will have with the EU.

Asked what would be better, a no-deal exit or a further extension, she replies that the best outcome would be an agreement.

He's got the backing of the 27 member states - now Boris Johnson is set to speak to waiting reporters in Brussels.

The EU chiefs are asked what they would say to Arlene Foster, the leader of the DUP - the Northern Irish party which is refusing to back the new deal.

The DUP's support - or lack of - could be critical at getting Boris Johnson's deal passed, as Mr Johnson does not have a working majority of his own MPs in Parliament.

Donald Tusk says the question is "not for me" to answer, gesturing to Leo Varadkar to respond instead.

But Mr Varadkar also dodges the question, saying: "I think I'll pass on that question too if you don't mind."

And asked what his message would be to the 48% of British voters who backed Remain in the EU referendum, Jean-Claude Juncker replies: "I would like to say to the 48% that they were right."

Did the EU shift any of its red lines, Donald Tusk is asked by a Politico journalist.

He says the EU side were always open in the negotiations.

"Without our goodwill and very constructive approach, any kind of deal was impossible," Mr Tusk said.

He said now the ball was in the UK's court, adding that he has "no idea" what would happen.

But interestingly - after Jean-Claude Juncker's comments earlier that there was no need to extend the Brexit deadline - Mr Tusk said if there was a request for an extension, he would consult EU members.

"What we have is a revised agreement, a new solution, a unique solution which recognises the unique history of Northern Ireland," said Irish Taoiseach Leo Varadkar.

He said it is "different from the backstop... more likely to be used to come into force and could become permanent, but only with the consent of the elected representatives of Northern Ireland".

Now it's the turn of the EU's chief negotiator, Michel Barnier, who begins by thanking his colleagues for their hard work.

"I want to underline one point... while the subject matter may very often have been technical... what has mattered above all has been people in Ireland, in Northern Ireland," he said.

"For me, what really matters is the people of Northern Ireland and Ireland - and peace on the island of Ireland."

"United we stand, divided we fall," said Irish Taoiseach Leo Varadkar, saying that he has felt solidarity from the EU, despite Ireland being a "small" state.

"Like President Tusk, I have mixed feelings today," said Mr Varadkar, adding that he "absolutely" respects the UK's decision to leave.

"It's a little bit like an old friend going on an adventure without us," he said - but there will always be a place for Britain if it decides to come back.

Mr Varadkar said the new solution, which is an alternative to the backstop, kicks in for a four-year period and could become permanent with Northern Irish consent.
