Senior figures in Nigel Farage's Reform UK party have been filmed apparently conspiring to conceal illegal foreign donations, in an undercover investigation broadcast by Channel 4 News on Thursday. Journalists posing as a prospective donor and his wealthy American father — who under UK electoral law cannot donate to a British political party — arranged for the father to fund £30,000 worth of polling that benefited Reform, without the arrangement being disclosed to the Electoral Commission; footage shows a senior adviser appearing to suggest channelling further donations through the British-based son, while the party's head of policy said Farage "doesn't know, won't know" about the arrangement. Reform denied wrongdoing, dismissing the investigation as a hoax by "foreign-funded climate-change activists," but opposition leaders have called on police and the Electoral Commission to investigate, with the scandal breaking just as Farage was set to deliver his party conference speech boasting of record fundraising.
