U.K. Prime Minister Theresa May is stepping up the government’s preparations in case Brexit negotiations break down and the country crashes out of the European Union without a deal.

May is planning a top-level meeting of her cabinet ministers early in September specifically to discuss how to ready the U.K. for a no-deal Brexit, according to people familiar with the matter.

Separately, a working group of senior government officials is being convened to devise ways to keep the Irish border free of customs checks and police even if there’s no withdrawal agreement, one of the people said.

The U.K. is scheduled to leave the EU on March 29 but talks between the two sides are making painfully slow progress. Negotiations are stuck over two issues: May’s proposals for a new free trade area spanning the U.K. and the EU; and how to avoid a hard land border between the British province of Northern Ireland and the Irish Republic.

In July, May’s cabinet agreed at a meeting at her Chequers country retreat to step up preparations for departing from the bloc without an agreement and she’s reorganized the Brexit Department to focus on the task.
