Nigel Farage has stood down as leader of UKIP.
The MEP announced he would be stepping back from the position during a speech in London.
Mr Farage has said he had "done my bit" following the UK's referendum vote to leave the EU and had achieved the aim for which he came into politics.
The 52-year-old has had two stints as leader of the Eurosceptic party since 2006, and announced he was quitting the post after failing to win a Commons seat in the 2015 general election, only to change his mind days later.
In a speech in London setting out UKIP's strategy for the post-referendum period, Mr Farage said: "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."
In a statement released by Ukip, Mr Farage said: "The victory for the Leave side in the referendum means that my political ambition has been achieved. I came into this struggle from business because I wanted us to be a self-governing nation, not to become a career politician.
"UKIP is in a good position and will continue, with my full support, to attract a significant vote.
"Whilst we will now leave the European Union, the terms of our withdrawal are unclear.
"If there is too much backsliding by the Government and with the Labour Party detached from many of its voters then UKIP's best days may be yet to come".
He said the party was in a "pretty good place" and said he would not change his mind about quitting as he did after the 2015 general election.
Leading UKIP was "tough at times" but "all worth it" said Mr Farage and added the UK needed a "Brexit prime minister".
In the wake of the announcement, the party's only MP, Douglas Carswell, tweeted a smiley face emoji.
It comes days after Mr Farage said Mr Carswell could be booted out of the party because of his differing views to fellow members.
