Nigel Farage held the Ukip party leader from 2006 to 2009 and then again 2010 to 2015, resigning after the poor results from the 2015 general election.
But not to be deterred he came back for a third time, steering the country to Brexit (although not officially) and then quit his position again despite his party's "win".
Paul Nuttall took his place, but a disastrous general election in 2017 led him to step down as leader.
At a leadership election in September 2017, Henry Bolton came through with a surprise win at the party's conference.
However he stepped down after the controversy following reportedly racist comments his girlfriend Jo Marney made about Prince Harry's fiancée, Meghan Markle.
