Story highlights UKIP leader Nigel Farage played a key role in campaign for Britain to leave EU

Critics have accused him and his party of peddling racist and xenophobic views

London (CNN) Nigel Farage announced Monday that he will step down as the leader of the UK Independence Party, saying, "I've done my bit" to get Britain out of the European Union.

He said the party was "in a good position" following the EU referendum and that his political ambition had 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," Farage said.

"During the referendum campaign I said I want my country back. What I'm saying today is I want my life back."

Thank you to all my supporters in @UKIP and beyond. Delighted with the result we fought for so long to achieve. #BrexitBritain — Nigel Farage (@Nigel_Farage) July 4, 2016

It's not the first time Farage has said he would resign as the UKIP's leader. In 2015 he offered to step down after the election, but party members urged him to stay on.
