A stunned European Union vowed to remain united on Friday despite Britain voting to leave, as fears grew that a "chain reaction" of further referendums could tear the bloc apart.
As Brussels, Paris and Berlin woke up to the grim news, leaders warned of a difficult divorce in a sign that Britain will win few concessions in negotiating life outside the circle of the other 27 members of the bloc.
EU Parliament President Martin Schulz hoped the vote would not trigger a domino effect prompting other EU members to quit.
"The chain reaction that is being celebrated everywhere now by eurosceptics won't happen," he said.
