Efforts to reach a Brexit deal should "accelerate over the months to come", British Prime Minister Theresa May and European Commission chief Jean-Claude Juncker said in a joint statement Monday after a dinner meeting in Brussels.

"The Prime Minister and the President of the European Commission reviewed the progress made in the Article 50 negotiations so far and agreed that these efforts should accelerate over the months to come," the statement said, referring to the EU's divorce clause for states leaving the bloc.
