Nigel Farage's Reform UK has received £72 million from two cryptocurrency billionaires in less than 48 hours, an unprecedented injection of political money that has immediately reopened Britain's debate over how much influence a handful of extremely wealthy individuals should be allowed to wield over elections.

The first £36 million came from Ben Delo, the British co-founder of cryptocurrency exchange BitMEX. A day later, Christopher Harborne, a British-born crypto investor and longstanding Reform backer, announced that he would match Delo's contribution with another £36 million. The two donations are jointly the largest individual political contributions in British history and together exceed what either Labour or the Conservatives spent during the last general election campaign.

Both men are deeply connected to the cryptocurrency world. Delo co-founded BitMEX and pleaded guilty in the United States in 2022 to violating the Bank Secrecy Act after prosecutors accused the exchange of failing to maintain adequate anti-money-laundering safeguards. He was later pardoned by Donald Trump. Delo, who previously lived in Hong Kong, had already become central to Reform's finances: a £4 million donation earlier this year accounted for roughly 75% of the party's private donations during the April-to-June quarter.

Harborne's relationship with Farage goes back much further. An early investor in cryptocurrency and a shareholder in Tether, the company behind the world's largest stablecoin, Harborne has poured millions into political causes associated with Farage since the Brexit era. He was already Reform's largest historical donor before announcing the latest £36 million contribution. Earlier this year, Farage also faced scrutiny over a separate £5 million personal gift he received from Harborne in 2024, shortly before reversing his decision not to stand in that year's general election. Farage has said the gift was unconditional and denies breaking parliamentary rules.

The new money becomes even more politically sensitive because Reform has openly embraced cryptocurrency-friendly policies. The party has proposed reducing capital gains tax on digital assets, encouraging greater cryptocurrency adoption and establishing a bitcoin reserve at the Bank of England. Harborne, however, insists he expects nothing in exchange for his money no peerage and no policy changes while Farage says the donations will finally allow Reform to compete financially with Britain's established parties.

But the controversy extends beyond cryptocurrency. Britain has traditionally imposed few limits on how much a permissible individual donor can give to a political party. The sheer scale of the Delo and Harborne contributions has therefore intensified calls for a cap on political donations, with critics arguing that £72 million from two people gives wealthy individuals disproportionate influence over the democratic process. The Liberal Democrats have renewed calls for limits on donations.

There is another complication. Both donors have previously lived abroad. Harborne has been based in Thailand and also holds Thai citizenship, while Delo recently returned to Britain from Hong Kong. Legislation moving through Parliament would cap donations from some British citizens living overseas, as well as those who have recently returned, at £100,000 annually. The government says elements of the restrictions will operate retrospectively, raising questions over whether the £72 million could ultimately be affected. Reform insists both donations comply fully with existing Electoral Commission rules and UK law.

All this arrives while Reform is already facing separate allegations concerning its funding. Two senior Farage aides temporarily stepped down after a Channel 4 investigation alleged they had helped arrange for a US company to fund political polling for the party. Reform strongly denies wrongdoing and says it has broken no electoral laws. Police are assessing information relating to the allegations, while the Electoral Commission has been considering the claims.

For Farage, £72 million could transform Reform from an insurgent political operation into an election machine capable of matching Britain's traditional parties in advertising, staffing, campaigning and data.

But it also raises a simple question: Will this much money potentially influence the direction of an election?
