Former UKIP leader Gerard Batten is to stand for the position again, despite leaving the role less than a month ago.
Mr Batten quit as the party's leader on June 2, after it was defeated in the European elections by Nigel Farage's Brexit Party.
Announcing his plans to take part in the UKIP leadership race, he wrote on Twitter: "Because of overwhelming support from UKIP members I have decided to stand in the leadership contest.
"My platform will include: * National Democracy * Economic Democracy * Political Democracy * Freedom of Speech * No backtracking or surrender to political correctness."
He appears to be following in the footsteps of former UKIP leader Mr Farage, who resigned for the first time in 2009 before taking up the reins again in 2010, repeating this in 2015, and quitting for a third time in 2016.
The winner of the leadership race will be announced on August 10, and if Mr Batten is not re-elected, the winner will be UKIP's seventh leader in just under three years.
Former UKIP deputy leader, Mike Hookem has revealed that he will also be running for leadership of the party.
He quit his role as deputy under Mr Batten's leadership, saying he could no longer support him.
He said at the time: "Mr Batten's policy direction and associations have given the mainstream media the ammunition to label our party 'extreme' and 'far-right', accusations I do not believe to be true."
Senior UKIP members Ben Walker and Gareth Bennet will also be running for the role.
