Why is Farage’s Reform accused of violating the UK’s foreign funding rules?

The anti-immigration Reform UK party said two of its senior officials had stepped down on Friday, following allegations that they were secretly filmed appearing to discuss ways to circumvent UK electoral laws on foreign donations.

The far-right party, whose popularity has soared in the past two years, is already embroiled in several other funding scandals involving its leader Nigel Farage. On Friday, it announced an internal probe into the latest case, which was brought to light by a Channel 4 investigation.

Reform is currently holding its annual party conference in Birmingham, central England.

Here’s what we know about the foreign funding claims and how they could affect British politics.

Channel 4, an independent broadcaster, aired footage of senior Reform officials Dan Jukes and James Orr meeting with undercover reporters who were posing as prospective Reform backers from the United States.

In one instance during the programme, which was broadcast on Thursday night, footage was shown of Jukes appearing to talk about a proposal for Reform to receive a 500,000-pound ($675,000) donation from one of the men, who was presenting himself as an American financier, through his son, who he said lives in the UK.

The “son” was actually another journalist from investigative group Verbatim, which recorded the exchange.

In separate footage, Orr appeared to discuss a plan for the US donor to fund opinion polls for Reform UK rather than donating the money directly.
