European Union leaders are unlikely to agree at a summit this week on a delay to Britain’s departure, and will probably have to meet again next week, the head of the bloc’s executive branch said Wednesday. British Prime Minister Theresa May is expected to ask Brussels for a delay to Brexit, currently scheduled for March 29, ahead of the EU summit starting Thursday. Details remain unclear, but May’s troubles deepened when the speaker of the House of Commons ruled earlier this week that she can’t keep asking lawmakers to vote on the same divorce deal they have already rejected twice. Britain’s political chaos is causing increasing exasperation among EU leaders. Asked by Germany’s Deutschlandfunk radio what May would need to secure a delay this week, European Commission President Jean-Claude Juncker replied that “she must bring approval of the negotiated deal and she must bring clear ideas on timing.” “My impression is … that this week at the European Council there will be no decision, but that we will probably have to meet again next week, because Mrs. May doesn’t have agreement to anything, either in her Cabinet or in Parliament,” Juncker added.
