The European Parliament’s first debate on the UK’s vote to leave has been marked by bitter exchanges.
A central figure in the Leave campaign, UK Independence Party (UKIP) leader Nigel Farage, was booed, called a liar and accused of using “Nazi propaganda”.
Mr Farage shot back that the EU itself was “in denial”.
UK Prime Minister David Cameron is meeting leaders of the other 27 EU states for the first time since Thursday’s referendum.
“I’ll be explaining that Britain will be leaving the European Union but I want that process to be as constructive as possible,” he told reporters before the summit’s working dinner in Brussels.
An EU official close to the talks told BBC News the mood was “very, very serious” and a question mark hung over the UK’s next presidency of the EU, due to begin in the second half of next year.
“The leaders are very interested in hearing the UK’s timeline but everyone knows Cameron won’t trigger Article 50 [the first formal step in the withdrawal procedure],” the source added.
The announcement of Mr Cameron’s replacement as leader of the Conservative Party, and thus prime minister, is not due now until 9 September, with 12:00 BST Thursday as the deadline for nominations.
European Commission President Jean-Claude Juncker warned against delay in starting the exit process: “I don’t think we should see any shadow-boxing or any cat-and-mouse games. It is clear what the British people want and we should act accordingly.”
