Britain’s populist Reform UK said two senior aides to leader Nigel Farage stepped down on Friday after an undercover investigation alleged the party had broken electoral law by arranging for a foreign donor to pay for political polling.

Reform denied any wrongdoing and said it had been the victim of a hoax perpetrated by ⁠climate activists.

The governing Labour Party wrote to the police asking them to investigate possible criminal offences, including an alleged proposal to channel a larger overseas donation through a UK intermediary.

The investigation, broadcast by public British broadcaster Channel 4 just as Reform’s annual conference opened to the public, said two senior figures in Reform had arranged for a U.S. company to pay more than £30,000 ($40,000) for three opinion polls commissioned by the party.

Such an arrangement could breach British laws on political funding, which ⁠ban foreign donations.

Posing as wealthy donors from the United States with British connections, the ​undercover ⁠team from an investigative group called Verbatim said it spent a year speaking to top officials in Reform about possible donations, culminating in a lunch with Farage.

Channel 4 said Verbatim was an independent organisation founded by journalists from the Centre for Climate Reporting, but that it ⁠had verified their findings, which included covertly filmed footage of meetings.

Farage, a Trump ally and former Brexit campaigner who is under parliamentary investigation over earlier donations, ​told LBC radio: “The party ⁠has broken no laws. The party has not taken any ‌dodgy money or anything like that whatsoever.”

Party’s poll lead has faltered

Reform, which has seen its commanding lead in opinion polls falter over undeclared donor allegations, announced an internal investigation and said the two officials featured in the undercover filming — head of policy James Orr and Farage’s right-hand man Dan ‌Jukes — had stepped down pending its results.

Orr, a philosophy professor at the University of ‌Cambridge and friend of U.S. Vice President JD Vance, said in a video on X that Reform had not been involved in commissioning the poll.

“There’s absolutely no way this could amount to a benefit or donation in kind at all,” he said.

“It wasn’t internal party polling. It wasn’t Reform UK’s poll. It was a public poll arranged by an independent person paying an ⁠independent pollster, and those polls were published immediately for the general public.”

The latest accusations over donations come on the first public day of the party’s annual conference, which Farage had hoped would offer him a chance of a reset after a difficult summer.

Farage, 62, is being investigated by a parliamentary watchdog over a £5 million donation from crypto-billionaire Christopher Harborne in 2024. He denies any wrongdoing but has seen support for his party soften in recent weeks.

Labour allege further possible breaches

On Friday, Farage said both Jukes and Orr had “said things that shouldn’t have been said” in relation to donations purportedly originating in the United States, but no such donation had been accepted by the party and that the two had been “entrapped”.

In a letter to the Metropolitan Police, Labour said ‌the documentary contained two further possible breaches: discussion of channelling a donation from a U.S.-based donor through a UK-based son and the suggestion ​that similar methods have been used in the past.

A spokesperson for Reform said: “Reform UK has been the target of a hoax ‌perpetrated by foreign-funded, climate change activists posing as would-be party donors. The ⁠party denies any wrongdoing.

“Reform UK has a robust vetting process for prospective donors approved by the Electoral Commission.”

The Metropolitan Police said ⁠it was aware of the allegations in the broadcast and would assess any information provided to them. This did not amount to the formal launch of an investigation.

The Electoral Commission, which oversees ‌and regulates political finance in Britain, said: “We are ​considering all relevant information, in line with our regulatory remit, and we are ‌in touch with the Met Police.

“The Electoral Commission has not ​approved the donor vetting process for Reform, or any other party. Parties are responsible for ensuring their internal processes and controls are fit for purpose.”
