The EU summit conclusions, external are out now - just three paragraphs.
The EU is determined "to have as close as possible a partnership with the United Kingdom in the future", they say.
Back in the UK, two sides of the Conservative divide have spoken to Sophie Ridge on Sky this morning.
Housing Secretary James Brokenshire came down firmly behind the PM, saying the withdrawal deal "is in the best interest of our country". He says it's better than staying the EU, "given that people voted for us to leave the European Union" in the 2016 referendum.
On the other side, prominent Brexiteer Iain Duncan Smith says the deal has "conceded too much control" to the EU and undermines earlier pledges made by Theresa May.
He questions whether the deal genuinely ends freedom of movement and raises concern that Gibraltar has been "abandoned" by reported concessions to Spain.
No surprise to hear he won't be voting for the deal in Parliament in the coming weeks.

Luxembourg Prime Minister Xavier Bettel, going into the summit, says the deal "is the best possible one".
Both the EU and UK have made concessions, he added, with no alternative possible.
He called for more optimism about the deal. "We are going to organise a divorce... it's not a funeral."

A 585-page text spells out the terms of the UK withdrawal. It is legally binding.
And there is a much shorter political declaration - a roadmap for future ties post-Brexit, including ambitions for trade and wide-ranging co-operation.
Read about the key points here.

Former UKIP leader Nigel Farage, who remains a member of the European Parliament, says he'll be voting against the deal when it's put to MEPs.
Speaking to the BBC News Channel, he disagreed however that the deal was so bad that the UK would be better off remaining in the EU, as some have suggested.
"It's an awful deal, I want the deal rejected," he says.
Both a second referendum or the UK leaving without a deal altogether would be better alternatives, he added.
French President Emmanuel Macron says Brexit shows that Europe "needs rebuilding".
The UK's exit "shows that the EU is fragile in a way", he told reporters in Brussels.
But he voiced satisfaction that the negotiated UK withdrawal deal addressed the issues of competition rules and fisheries.
"It’s the choice of a sovereign people, it’s a moment for unity and responsibility," he said on Brexit.
Brexit: 'Time for everybody to take responsibility'
Even if a Brexit deal is "settled" in Brussels today, Mrs May still faces political difficulties at home.
Here's a quick guide.
European Commission President Jean-Claude Juncker says it is "a sad day... a tragedy".
"It's not a moment of jubilation," he says.
Asked about the chance of the deal being changed if it's rejected by the UK parliament, he said "this is the deal... the European Union will not change its fundamental position on this issue."
"I would vote in favour of this deal because it's the best possible for Britain," he added.
The 27 EU leaders are set to sign off Theresa May's Brexit deal in Brussels today.
But back at home, the PM will still face the huge hurdle of getting MPs to approve her EU withdrawal agreement and accompanying political declaration.
BBC political correspondent Ben Wright looks at what will happen if MPs reject Mrs May's deal.
Irish Prime Minister (Taoiseach) Leo Varadkar said "tariff-free, quota-free trade between Britain and Ireland is very important".
He also said it was important that the deal would keep the Common Travel Area after Brexit, which enables passport-free travel between the UK and Ireland.
Arriving in Brussels, President of the European Parliament Antonio Tajani says he "wants to be optimistic" about the chances of the deal going through both the UK and EU parliaments.
It is a good deal for both sides, he says, and the focus is now on working hard for good relations in future.
"The United Kingdom will leave the European Union but not Europe, it's important we have a good a relationship."
The European Parliament will vote on a Brexit resolution in December and expects to vote on the agreement in January or February, he says.
