Nigel Farage is the latest UK politician to jump the Brexit ship, announcing his shock resignation in a press conference on Monday.
Who is Mr Farage, and why is this news so important? Here are the five things you need to know about his exit.
Nigel Farage is the leader and founding member of the UK Independence Party (UKIP), which was behind the campaign to get Britain to leave the European Union.
He's led the party for the last eight years, but has stood down twice before - in 2009 and again last year. This time, he says it's for good.
Even though Mr Farage says he's gone from UKIP for good, he's raised the possibility of a role negotiating Britain's exit from the EU.
But he's a controversial figure: critics accuse him of peddling racist and xenophobic views.
He has long campaigned against Britain's open immigration policy, saying it's led to an influx of people who have damaged cohesion and created divisions within society.
Now the Brexit vote has succeeded, Farage says he's got what he came for.
"During the referendum I said I wanted my country back… Now I want my life back," he said on Monday.
Mr Farage's resignation comes at a time of huge instability in UK politics.
The Conservatives are also searching for a new leader after David Cameron's post-Brexit resignation.
The Labour Party is in turmoil too, with leader Jeremy Corbyn losing the support of most of his MPs after being unable to stop the Brexit.
Mr Farage sees this as a chance for UKIP - which currently only has one MP in the UK parliament - to establish more of a foothold.
The race to find a successor will now begin, with possible candidates including the party's deputy leader Paul Nuttall, who has already put his hand up.
"We have some fantastic opportunities to move on and benefit from the mess that the Labour party's in," Mr Nuttall said.
Mr Farage says he won't be backing any particular candidate but is adamant the party will have a new leader by their conference in September.
