The Guardian's investigation into Reform UK's finances has uncovered a complex web of relationships and transactions involving Nigel Farage, billionaire donor Christopher Harborne, and convicted fraudster George Cottrell. The disclosures have led to police interviews and parliamentary probes, raising questions about the party's funding sources.
Key revelations and their impact
Three months ago, the Guardian revealed that Farage accepted a £5m gift from Harborne. Since then, the investigation has detailed secret donations, a behind-the-scenes loan, and the Metropolitan police interviewing two people under caution. Sources say bank staff at several institutions were so concerned about transactions involving senior Reform figures that they reported them to the National Crime Agency.
Financial industry sources told the Guardian that George Cottrell transferred over $2m to his mother, Fiona, in 2024, with each sum arriving shortly before she made substantial donations to the party. Fiona, of aristocratic roots but modest means, secretly gave £1m to Britain Means Business, a Reform fundraising vehicle controlled by Richard Tice, on 10 June 2024. Half of that sum was immediately transferred to the party despite banker queries to Tice about the funds' origin.
The incestuous relationships at the core
Farage is friends with Cottrell, who is described as an unpaid adviser to Reform. Cottrell is also friends with Harborne, who has given millions to the party. Tice, Farage's deputy, says he has known the Cottrell family for 50 years, and George has lent money to Tice. These five people are central to a party that believes it can form the next government; without them, Reform would not exist in its current form.
Scrutiny has provoked Farage into various explanations for accepting the £5m gift, including broad claims of an establishment plot. Instead of answering the Guardian's questions, he and other senior figures have sent threatening legal letters or attempted to undermine stories with pre-emptive interviews in the Daily Telegraph. Farage has also made unsubstantiated claims about illegal hacks involving Russia and state-orchestrated leaks.
George Cottrell's controversial background
Cottrell, known as 'Posh George', has been at Farage's side for at least a decade. In January, the Guardian reported on his alleged role as a frontman for the betting syndicate of Tony Bloom, a megastar gambler and football proprietor. Court documents claimed Cottrell earned millions by allowing Bloom's syndicate to place bets using accounts in his name and had a financial interest in the offshore gambling outfit Tether.bet. He allegedly approached UK gamblers to use Tether.bet despite it lacking a UK gambling licence.
Cottrell's lawyers have repeatedly said he was not a director or shareholder of Tether.bet and did not comment on the court proceedings as he was not a party to them. Cottrell, who could not afford legal representation when arrested in the US in 2016 and relied on family assistance, has seen a rapid reversal in his fortunes since his release from prison in 2017, now pursuing a costly, jet-set lifestyle based in Montenegro.
Farage's financial turnaround and unanswered questions
Farage, who said he was 'skint' in 2017, now owns several houses and has shown anger when asked about his wealth and the £5m gift. 'Literally none of your business,' he told the BBC. The £5m came via a deed of gift in April 2024, just as Farage, then Reform's main shareholder, weighed his political future. Sources claim some of the £5m was not transferred until just before he declared he would stand in the 2024 general election. Harborne's lawyers say the gift was unconditional and that Harborne did not foresee Farage returning to politics.
The Guardian has also revealed that Cottrell lent Tice's company, Tisun Investments, £78,100 in late 2024. Tice says this was a 'bridging loan' that was repaid after he made a £613,000 donation via the same company to Reform. Cottrell's support to Farage and Tice, however, pales in comparison to the apparent largesse extended to the party through his mother's donations.
Ongoing investigations and the path ahead
Fiona Cottrell and George Cottrell have been interviewed under caution as part of a police investigation into the 2024 donations. Fiona has not responded to contact attempts, and George has not denied giving his mother large sums; his lawyers say any political donations were entirely her decision. Two parliamentary standards investigations are due to conclude in the autumn: one into the £5m gift to Farage and another into his benefits from Cottrell. The Metropolitan police investigation continues.
Reform UK is learning that with great success comes ever greater scrutiny. The tangled financial web at the heart of the party raises serious questions about transparency and accountability, which remain unanswered.
