Round of talks don't resolve Brexit problems ahead of summit

BRUSSELS -- A flurry of talks between Britain and the European Union ended Sunday without a Brexit agreement, leaving the two sides three days to close a gap in their positions before a make-or-break summit.

An unscheduled, face-to-face meeting between EU negotiator Michel Barnier and British Brexit Secretary Dominic Raab, and a hastily scheduled meeting of 27 EU ambassadors in Brussels, had sparked speculation the long-awaited deal was imminent.

Barnier dashed those hopes Sunday evening, writing on Twitter: "Despite intense efforts, some key issues are still open" in the divorce talks. The key stumbling block remains the need "to avoid a hard border" between Ireland and the U.K's Northern Ireland after Brexit, he said.

British Prime Minister Theresa May is under intense pressure from her Conservative Party and its parliamentary allies not to give any more ground in negotiations, especially on the border issue.

The British government said in a statement issued Sunday night there were still "unresolved issues" but insisted negotiators had made "real progress" toward a divorce agreement.

The lack of a breakthrough on the border increased the chances the Brexit negotiations will fail to produce an agreement spelling out how the EU will interact with its former member and vice versa. EU officials have warned that real progress is needed at the summit starting Wednesday.

The British government said it remained committed to making progress at the summit. An EU official said no further negotiations were planned before the leaders of EU countries convene in Brussels. Both sides previously agreed a special November meeting -- to be called only if there is enough progress this week -- would be the deadline for reaching an agreement since Britain is set to leave the EU on March 29.

The EU and the U.K. are seeking an elusive compromise position on the difficult Irish border question ahead of the summit. The "Irish backstop" is the main hurdle to a deal spelling out the terms of Britain's departure from the EU and future relationship with the bloc.

After Brexit, the currently invisible frontier between Northern Ireland and Ireland will be the U.K.'s only land border with an EU nation. Britain and the EU agree there must be no customs checks or other infrastructure on the border, but do not agree on how that can be accomplished.

Raab, Britain's Brexit secretary, was not expected in Brussels on Sunday, but he made a last minute trip for an in-person meeting with Barnier.

"With several big issues still to resolve, including the Northern Ireland backstop, it was jointly agreed that face-to-face talks were necessary," Raab's office said.

The EU's "backstop" solution -- to keep Northern Ireland in a customs union with the bloc -- has been rejected by Britain because it would require checks between Northern Ireland and the rest of the U.K.

The alternative -- to keep the entire U.K. in a customs union until a permanent solution can be found -- has outraged pro-Brexit members of May's divided government, who claim that approach would limit the country's ability to strike new trade deals around the world.

The idea is also anathema to the Democratic Unionist Party, a Northern Ireland Protestant party that props up May's minority government.

So even if May strikes a deal with Brussels, she will struggle to get it past her government and Parliament at home.

Raab's predecessor, David Davis, wrote in the Sunday Times that May's plans for continued close economic ties with the EU even after Britain leaves the bloc is "completely unacceptable" and must be stopped by her ministers.

May is struggling to build a consensus behind her Brexit plans ahead of a Cabinet meeting Tuesday that will be followed by Wednesday's EU summit. If Davis' call for a rebellion is effective, the Cabinet meeting is likely to be fractious.

Davis and former Foreign Secretary Boris Johnson resigned from May's Cabinet this summer to protest her Brexit blueprint. While all three are members of the ruling Conservative Party, the two men have become vocal opponents of May's plan, saying it would betray the Brexit vote and leave Britain tied to the EU without any say over its rules.

Johnson, who regularly uses his newspaper column in the Daily Telegraph to excoriate May's Brexit plan, said the EU's border backstop amounted to "a choice between the breakup of this country or the subjugation of this country, between separation or submission."

"It must be rejected, and it must be rejected now," he wrote in today's edition.

May's Brexit plan has also been rejected by leaders of the main opposition Labour Party, further dimming the prime minister's hopes of winning parliamentary backing for any Brexit deal she reaches with EU officials.
