Britain's Prime Minister Theresa May spoke with European Commission president Jean-Claude Juncker Sunday evening ahead of a crucial Brexit vote, but talks between the two parties remain "deadlocked," British media report.
Why it matters: May faces a substantial loss if she presents to members of Parliament a deal that's largely unchanged for Tuesday's "meaningful vote." She's been trying to achieve changes to the Brexit agreement with the European Union to avoid Britain remaining indefinitely in a customs union and to maintain an open border on the island of Ireland — known as the "Irish backstop." However, the E.U. is reluctant to change the existing deal. Now, May's under pressure to delay Tuesday's vote. Talks were expected to resume Monday. Britain is due to leave the E.U. on March 29.
