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

The anti-immigration Reform UK party announced that two of its senior officials stepped down following allegations they were filmed discussing ways to circumvent UK electoral laws on foreign donations. A Channel 4 investigation revealed that Dan Jukes and James Orr met with undercover reporters posing as prospective American backers. Jukes was filmed proposing a £500,000 donation, while Orr discussed a plan to fund opinion polls instead of making a direct donation.
