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 has arrived in Brussels for his first talks with leaders of the other 27 EU states 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 going in to meet his counterparts.
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.
