BRUSSELS (AP) — The European Union's executive branch is calling on British Prime Minister Theresa May to speed up negotiations on how to leave the bloc and define its future relationship with the 27 remaining member states.

EU Commission President Jean-Claude Juncker told EU legislators Tuesday that "there is increasing urgency to negotiate this orderly withdrawal," showing frustration May had yet to clearly outline what she wanted once Britain leaves the bloc in March next year.

Juncker said the EU needs "further clarity" on such issues like a trading relationship and the EU's only land border with the U.K. on the island of Ireland.

The European Parliament's chief Brexit official, Guy Verhofstadt said that in three keynote addresses, May "is mainly repeating the red lines that we know already for two years."
