He's been accused of making the party all "about him" and now Nigel Farage has dismissed Ukip's founder because "no one cared who he was."
In a sensational interview, the UKIP leader slammed the founder and former leader of Ukip, Professor Alan Sked, branding him a "fully up paid member of the bitter and twisted club."
"Will anybody watching this video have ever heard of his name? When he was leading the party none cared who he was," he said in an interview with ChatPolitics.
Professor Sked has publicly denounced Farage's leadership, saying the party he launched in 1993 has become "extraordinarily right-wing" and is now devoted to "creating a fuss, via Islam and immigrants."
"They're not an intellectually serious party. Their views on immigrants and on [banning] the burqa are morally dodgy," he told HuffPost.
But Farage, who hasn't spoken to the party founder for 17 years, said the former leader's opinions are irrelevant.
"Who is he?" He questioned. "I don't respond to anything he says."
His comments follow Ukip's former chief executive accusing Farage of viewing the party as "being about him."
Will Gilpin, who quit after just eight months in the job, slammed Farage for stubbornly refusing to loosen his grip on power.
Ukip's failure to adopt a more professional management system means it will remain "a bunch of enthusiastic amateurs having a good time", he warned.
But Farage said the criticism was "unjust and invalid."
"It's better to be a one-man party than a no-man party," he said.
"At least people know who I am and what I stand for."
Moving onto the topic of gay marriage, the Ukip leader said his party "haven't discussed it," before adding they thought it could be "illiberal."
"We said that we felt that there was a great risk that if gay marriage went through it could prove to be profoundly illiberal," he said.
"There is very real legal risk that faith communities could be forced to conduct such ceremonies which would be illiberal because it would stop people pursuing some of their own beliefs," he added.
UKIP is opposed to the Government's proposals to legislate to extend the definition of marriage to include same-sex couples, with a statement from the party arguing civil partnerships are sufficient.
"Civil partnerships represent an entirely common sense way of allowing gay men and women in our country to register in a formal way their longterm commitment to one another," it reads.
"Gay marriage is an entirely different thing altogether."
