Nigel Farage has come under fire from EU president Jean Claude Juncker for attending an emergency session of the European Parliament to discuss the fallout from the Brexit vote.
The Ukip leader took his place along with other MEPs in the Brussels chamber as Mr Juncker addressed members about the next steps.
"That's the last time you are applauding here," Mr Juncker said after the fiercely anti-EU politician applauded his opening statement that Europe "must respect British democracy and the way it has expressed its view".
"To some extent I am really surprised that you are here," he told him.
"You were fighting for the exit, the British people voted in favour of the exit. Why are you here?"
Also at the EU summit, German chancellor Angela Merkel has said Britain "cannot expect to have no more obligations but keep the privileges" of EU ties.
