The Metropolitan Police are investigating about £500,000 in donations made to Reform UK by Fiona Cottrell, the mother of George Cottrell, a convicted fraudster and an associate of Nigel Farage. Multiple reports say the inquiry focuses on whether the May 2024 donations—two payments of £250,000—were structured or intended to conceal the identity of a donor who would not be permitted to make a donation. The investigation is described as relating to alleged “evasion of restrictions on donations.” Reports also state that police interview people under caution as part of the inquiry. Reform’s deputy leader Richard Tice has said the allegations amount to a politically motivated smear campaign. Some outlets add further related claims, including that Fiona Cottrell may also have made a larger £1 million payment to a company connected to Tice, with part of that amount later donated to Reform, though the relationship to the police probe is not confirmed across sources. Separately, the broader political context includes scrutiny of other Reform fundraising questions involving Farage.
