ITV News says one of its undercover reporters was asked if he would consider standing to be a councillor, after spending time leafleting with Reform activists.
He meets with the chairman of a local Reform branch in Chester, Ian Frost, who describes the meeting as “the first stage” of the vetting process.
After the reporter says he has previously posted in support of Robinson on social media, Frost advises him to delete the posts.
“Anything where you’ve got, things, Tommy Robinson or anything like that, okay, I would delete the account and I’d start again,” Frost adds.
Farage has said Robinson would not be allowed to join Reform.
Frost later suggests the undercover reporter could apply to stand for the party, saying: “You might become a councillor. You might then want to go to the MP route. So, social media, yeah. And apply.”
Frost told ITV News he thought the reporter was a genuine candidate and gave him the benefit of the doubt.
He added that it was not fair to judge people on a single conversation and he had since left Reform for unrelated reasons.
In another part of the film, a former Reform candidate – Alex Lomas – claims he failed the party’s vetting process twice, including for sharing social media posts from Robinson.
However, Lomas says a few days after he failed for the second time he was asked to stand for the party.
“On my second application, I got declined on the Friday, I got an email from them on the Tuesday saying you’ve passed vetting,” he is recorded as saying.
“I said, well, I think you better check with your paperwork, mate, because I’ve just failed on Friday. Now, you’re saying I’ve passed it, I’ve not changed anything.
“And then I got a phone call a few days later. Hi, will you stand for Reform UK? I’m like, yeah okay.”
He stood for Reform in local elections in Oldham in May but did not win a seat on the council.
The has not been able to contact Lomas and he did not respond to requests for comment from ITV News.
Reform denies Lomas failed vetting in the first place.
ITV’s undercover report also shows Farage ruling a controversial mayoral candidate Dr Chris Parry – who said the then Deputy Prime Minister David Lammy should go home to the Caribbean – should be made to apologise, but not stand down.
In a conversation at Reform’s headquarters, the party’s director of communications Ed Sumner suggests Farage is “protecting” Parry.
In response Farage says: “It’s showing a bit of sorrow.”
In a separate conversation several weeks earlier, where Farage was not present, Sumner is recorded saying Parry is “clearly a racist” and “needs to go”.
After apologising to Lammy in January, Parry was allowed to remain Reform’s mayoral candidate in Hampshire and the Solent until he was later suspended in March “pending investigation”, following comments about a Jewish voluntary patrol service.
Parry told the there was never an investigation and he has since left the party.
He said: “I would urge people to go back to the original contexts and tweets to see what was said and why. They related to reparations and failures by the police and government.
“They will see I always exercise my right to criticise anyone in power or the public eye, whom I judge to be acting against the interests of the British people.”
Labour Party chairwoman Bridget Phillipson said: “These latest shocking and deeply disturbing revelations go right to the top of Reform UK.
“Nigel Farage needs to wake up and realise the buck stops with him. He also must urgently explain why he allegedly stood by a blatant racist instead of kicking him out of his party.
“Time and again Farage has had every opportunity to demonstrate leadership and get Reform’s house in order and every single time he has failed.”
