Luxembourg (dpa) - The 27 remaining EU countries are today in Luxembourg discussing the opportunities for a Brexit agreement with Great Britain. Chief negotiator Michel Barnier wants to report to the European Affairs Ministers, whether in the negotiations since Saturday came closer to a solution. Ultimately, the question is whether at the EU summit on Thursday an agreement on a regular exit of Great Britain on 31 October could succeed. Otherwise, it is likely to be talked about an extension of time. The dispute over open borders between Ireland and Northern Ireland is still struggling for details.
