European Union's chief Brexit negotiator Michel Barnier
European Union negotiator Michel Barnier said on Friday a Brexit deal with the United Kingdom was 90 percent done, although there was still a chance no accord would be reached due to ongoing stumbling blocks over the Irish border.
"Ninety percent of the accord on the table has been agreed with Britain," Barnier told France Inter radio.
"I'm convinced a deal is necessary, I'm still not sure we'll get one," he said.
On Thursday, British Prime Minister Theresa May and other EU leaders voiced renewed confidence that they could secure a Brexit deal, yet the two sides remain at odds over how to deal with their only land border, between the British province of Northern Ireland and Ireland.
May had also signalled she would consider extending a so-called transition period "for a matter of months" after Britain leaves the EU in March.

The European Union and Germany's government will not block an extension of the post-Brexit transition period, but an extension alone will not solve the problems on hand, European Affairs Minister Michael Roth said on Friday."If that solves problems and if a few more months are needed to negotiate the details of future relations, then it will certainly not fail because of the EU-27 and because of us in Berlin," Roth told German broadcaster WDR."But an extension alone does not solve the problems," he added."
