David Bull has been revealed as the new chairman of Reform UK after Zia Yusuf dramatically quit the role last week.
During a press conference in Westminster on Tuesday, Nigel Farage said the former NHS doctor and Most Haunted Live! presenter would bring "terrific verve, energy, enthusiasm" to the job.
He added: "It's going to be great fun".
Dr Bull is a popular figure among Reform members after joining Mr Farage’s team when he became an MEP for the Brexit Party in 2019.
The doctor-turned-TV presenter, 56, was born in London but grew up in rural Suffolk before studying medicine at Imperial College.
He replaces Mr Yusuf who suddenly quit the party last week, before returning two days later to run Reform’s Donald Trump-inspired DOGE cost-slashing unit.
Speaking at the press conference, Mr Yusuf said that he is "hugely excited" that Dr Bull was taking the role.
"I wholeheartedly congratulate him and I know he's going to do an incredible job for us," he added.
Mr Yusuf announced on Thursday that he was quitting the role he has held for almost a year.
It followed him branding comments made by the party's newest MP about a burka ban as "dumb".
Sarah Pochin, who last month was elected as MP of Runcorn and Helsby in Cheshire, asked Sir Keir Starmer whether Britain will join the likes of France and Denmark in banning the garment being worn in public.
Ms Pochin, a former Conservative councillor, urged Sir Keir to ban the clothing "in the interests of public safety" during her Prime Minister's Questions debut last Wednesday.
Mr Yusuf, a self-described “British Muslim patriot” who was seen as a key ally of Mr Farage, suggested she should have chosen a different topic.
But he rejoined the party on Saturday, just days after the fallout.
Mr Farage said he was "delighted" and confirmed his former chairman would now take on a more public role for the party, appearing more frequently in the media.
He said: "Zia regrets what he said and did the other day. It was a combination of 11 months [of] hard work and exhaustion."
Mr Yusuf said he had received a large number of messages urging him to reconsider leaving.
"After 11 months of working as a volunteer to build a political party from scratch, with barely a single day off, my tweet was a decision born of exhaustion," he said.
