Top European Union officials are hunkering down in Brussels trying to work out what to do next after the shock decision by British voters to leave the 28-nation bloc.

European Commission President Jean-Claude Juncker is hosting talks Friday with the leaders of the European Council and Parliament, along with Dutch Prime Minister Mark Rutte, whose country holds the EU's rotating presidency.

The four will try to agree on a European position on the vote, which could see a member country leave the bloc for the first time ever, ahead of a summit of EU leaders in Brussels starting on Tuesday.

Parliamentary leaders were meeting separately, and European commissioners — the EU's executive body — could hold separate talks later.
