The Metropolitan Police is assessing allegations of potential breaches of political donation law involving Reform UK after an undercover investigation aired by Channel 4 News.
The allegations centre on claims that senior Reform figures discussed arrangements under which polling commissioned by the party would be paid for by what they believed was an American-backed company.
The supposed overseas donors were in fact part of an undercover operation run by investigative group Verbatim, whose findings were later verified and broadcast by Channel 4 News.
The Metropolitan Police has stressed that it has not launched a criminal investigation at this stage. It said it was aware of media reporting concerning political party donations and an alleged breach of the Political Parties, Elections and Referendums Act 2000 relating to polling, adding that it would assess the matter and any information provided to it.
Polling worth £32,500 at centre of allegations
According to the Channel 4 investigation, three opinion polls costing a total of £32,500 were commissioned by Reform UK and paid for by the undercover operation through a US-linked company.
Reform figures involved in the discussions believed the funding came from a wealthy American backer and his UK-based son.
The legal issue is whether the arrangement, if it had been genuine, would have amounted to an impermissible political donation or a donation in kind that should have been declared.
Foreign companies are generally not permissible donors to UK political parties, while payments that meet costs on behalf of a party can fall within political donation rules depending on the circumstances.
Reform denies wrongdoing
Reform UK strongly denies that it broke electoral law and has described the undercover operation as a politically motivated hoax.
The party says it has robust vetting procedures for prospective donors and has legal advice supporting its position that no laws were broken.
Reform argues that the polling did not amount to a declarable donation because it was paid for by a private individual to a private company and subsequently provided to national newspapers rather than being retained as internal party polling.
Those claims have not been tested by a court or regulator.
Police assessment follows political referrals
The Liberal Democrats reported the allegations to the Metropolitan Police and the Electoral Commission following the broadcast.
Labour has also said it intends to refer the matter to police, while the Greens have called for an investigation.
The Electoral Commission said political parties are required to report permissible donations above the relevant reporting threshold and impermissible donations above £500.
It added that information concerning any potential attempt to evade controls on political donations is a matter for the police to consider.
No criminal finding has been made
The Met's involvement is currently limited to assessing the allegations and any material passed to officers.
There has been no announcement of a formal criminal investigation and no finding that Reform UK, Nigel Farage or any individual connected with the party has committed an offence.
That distinction is important because the central claims originate from an undercover investigation and remain allegations.
Two senior Reform figures step down
The story developed further on 4 September when Reform UK confirmed that head of policy James Orr and senior aide Dan Jukes had stepped down from their roles pending an internal party investigation.
Reform said it had launched an inquiry following the Channel 4 News broadcast and that the process should proceed independently and without prejudice.
Their decision to step down does not amount to an admission of wrongdoing, and the party continues to deny that it breached electoral law.
Farage appeared in undercover footage
The undercover team also filmed a meeting involving Reform leader Nigel Farage and individuals posing as the American donor and his UK-based son.
Channel 4 reported that Farage praised the impact of the polling during the meeting. Reform maintains that the wider operation was a hoax designed to entrap party figures.
The programme also alleged that a potential future donation of £500,000 was discussed, including possible methods for routing money through a UK-based intermediary.
No such £500,000 donation was completed.
What happens next?
The immediate question is whether the Metropolitan Police decides that the material supplied to it reaches the threshold for a formal investigation.
Reform's own internal inquiry is now also under way following the decision by Orr and Jukes to step aside.
Until either police, prosecutors, a court or the Electoral Commission reaches a formal conclusion, the claims should continue to be treated as allegations rather than established breaches of electoral law.
