Here's a bit more from Angela Merkel's press conference this afternoon.

She said the EU27 told Theresa May it was "important for us that the future relationship between the EU and the UK should be a relationship in which each partner can freely develop".

She added: "What is important for us is that first and foremost there is no renegotiating or amendment of the Withdrawal Agreement, the single market is guaranteed and the Good Friday Agreement is preserved."

The press conference is still going on - there may well be Brexit questions coming shortly.

The two presidents have been making statements about how the summit has gone in general - we're yet to hear many details on discussions about Brexit.

A joint press briefing from Jean-Claude Juncker, European Commission president, and Donald Tusk, president of the European Council, begins.

French President Emmanuel Macron stressed that "there is one deal, the only one possible" on Brexit.

On the controversial Northern Ireland backstop, he told a press conference: "we can give assurances, there is much concern about the backstop… it's not our goal, not a durable solution".

He said "we reaffirmed our readiness for dialogue, it's now in the hands of the UK Parliament".

Belgian Prime Minister Charles Michel has addressed a press conference too.

He said: "The ball is now politically in the British court."

He said there had been no agreement to hold a special Brexit summit in January, adding that the EU and Belgium must "accelerate" preparations for a disorderly UK exit.

Mr Michel added: "The risk of no deal is real."

Asked whether the EU could give more Brexit assurances, the German chancellor said they already had and they were contained in the conclusions made on Thursday evening, adding: "That is our position."

Jean Quatremer, veteran Brussels correspondent of the leftist French daily Liberation, paints a grim picture (in French) of the Brexit talks, external.

In an analysis piece he says Theresa May "hardly shone in her attempts to persuade the 27 [other leaders]".

She got "verbal assurances, but no legal commitment, nor any commitment to renegotiate the divorce contract".

There have been more questions about that conversation between Theresa May and Jean-Claude Juncker earlier.

Ms Merkel is asked about it, but says she doesn't want to comment on "what has been discussed in that format".

Angela Merkel says the EU27 have "tried to take up the concerns made by Great Britain" but that it is "important there is no renegotiation of the agreement".

German Chancellor Angela Merkel, giving her own press conference in Brussels, repeats the message that the EU doesn't want a "disorderly Brexit".

The deal made in November still stands, she says.

She said Theresa May had spoken about concerns about the backstop, adding that the EU sees it as an "insurance policy" only.

Environment Secretary Michael Gove has said that Theresa May's Brexit deal can survive.

While he didn't say how he thought the agreement would get through Parliament, he praised her "determination and focus".

Mr Gove was speaking at the Journalist's Charity Scotland lunch in Glasgow today.

The former journalist told the charity event he has had "unnerving and surreal moments" over the past week, including being followed outside Westminster by a man dressed as Santa who was protesting about Brexit.

The Brussels correspondent of German news website Spiegelonline, Markus Becker, says the two-day EU summit (which has now concluded) was a "disaster" for Theresa May.

In a video commentary (in German), external he says the other 27 EU member states are "losing patience" with the UK.

"The EU apparently has no desire to help her out of this jam," he comments.

In the EU's summit conclusions on Brexit, he says, "it is implied that intensive preparations will be made in case the talks break down and the UK leaves the EU chaotically".

"Apparently the EU has lost faith that this withdrawal deal can get through the British parliament. What you hear everywhere here is that, whatever extra assurances are given to May, they'll hardly lead the Brexit hardliners to change their minds."

The EU summit has officially ended.

EU leaders Donald Tusk and Jean-Claude Juncker are expected to give a news conference soon, as are national leaders.

The Labour leader has been commenting on the prime minister's Brussels statement.

Here's what he had to say:

The Italian media sees an uncertain future for Theresa May after the Brussels summit failed to leave her with the guarantees she wanted to secure her Brexit deal.

Liberal newspaper La Repubblica said: "Theresa May has returned from her Brexit mission impossible in Europe empty-handed again.

It said the summit had changed nothing for the prime minister and that the "future still looks extremely uncertain".

Il Sole 24 Ore, a business newspaper, published an interview with the chairman of the economic and monetary affairs committee at the European Parliament, Roberto Gualtieri, who said the Brexit agreement would not to be changed.

"This is the only agreement possible on the basis of the red lines set by the UK," the paper quoted Mr Gualtieri as saying.

It has not, as a journalist pointed out at the press conference earlier, been an easy week for Theresa May.

She may well be looking forward to this weekend more than usual - but she might not quite have that Friday feeling, as the future remains far from certain.

While she won the vote of confidence, hastily arranged on Monday, it was hardly a resounding victory for the PM with 200 backing her, but 117 opposing her. The cracks in the Conservative party are showing.

This is something the BBC political correspondent Nick Eardley has been taking a look at this week, as he asks how long Mrs May can cling on to power.
