The leader of Britain's anti-European Union UK Independence Party Nigel Farage says he is standing down after having realised his ambition of winning last month's referendum in favour of Brexit.

"I have never been, and I have never wanted to be, a career politician. My aim in being in politics was to get Britain out of the European Union," he told reporters.

"So I feel it's right that I should now stand aside as leader of UKIP.

"During the referendum campaign, I said 'I want my country back'. What I'm saying today, is, 'I want my life back,' and it begins right now."
