Exactly 1,000 days after Britain voted to leave the European Union, and nine days before it is scheduled to walk out the door, Prime Minister Theresa May hit the pause button, asking the bloc to postpone the U.K.’s departure until June 30, the Associated Press reported. EU leaders will only grant the extension if May can win the U.K. Parliament’s approval next week for her twice-rejected Brexit deal. Otherwise, the U.K. is facing a chaotic “no-deal” departure from the bloc within days, or a much longer delay that May says she will not allow while she is in power. May, who has spent two and a half years trying to lead Britain out of the EU, said it was “a matter of great personal regret” that she had to seek a delay to Brexit. In a letter to European Council President Donald Tusk, May acknowledged that the Brexit process “clearly will not be completed before 29 March, 2019” — the date fixed in law two years ago for Britain’s departure. May asked to delay Britain’s withdrawal until June 30, and said she would set out her reasons to EU leaders at a summit in Brussels on Thursday. Her longshot plan is to hold a third vote in Parliament on her deal next week, then use the EU-granted extension to pass the legislation needed for an orderly departure from the EU. May’s request — and Tusk’s response — leaves Britain and the bloc facing Brexit uncertainty right up to the deadline for departure. Withdrawing without a deal could mean huge disruptions for businesses and U.K. residents, as well as those in the 27 remaining EU countries.
