The Conservative Party has formally requested that HM Revenue and Customs investigate whether Nigel Farage, the leader of Reform UK, owes tax on a £5 million gift he received from a cryptocurrency billionaire. The party chair, Kevin Hollinrake, wrote to the tax authorities on Wednesday, questioning whether the payment from Christopher Harborne was in fact compensation for Farage's decision to stand as a candidate in the general election.
The development marks a significant escalation in political tensions surrounding Farage's finances, as the Reform UK leader has faced growing scrutiny over his ties to wealthy donors and the sources of his income. Hollinrake's letter to HMRC argues that the £5 million transfer may not qualify as a tax-free gift under UK law, but rather as a payment linked to Farage's political activities, which could be subject to income tax or national insurance contributions.
Christopher Harborne, a Thai-born British businessman who made his fortune in cryptocurrency trading and aviation fuel, has been a prominent backer of Reform UK. The £5 million payment to Farage was disclosed in the register of members' interests earlier this year, but the circumstances surrounding the transfer have raised questions among political rivals and transparency campaigners. The Conservatives have seized on the issue, accusing Farage of benefiting from opaque financial arrangements that lack the transparency expected of a party leader.
In his letter, Hollinrake specifically asked HMRC to determine whether the payment was made «to compensate Mr Farage for running to be an MP» or for other services rendered, which would change its tax treatment. The Conservative chair also requested that the tax authority examine whether any other payments from Harborne to Farage or Reform UK entities have been properly declared and taxed. A spokesperson for HMRC confirmed receipt of the letter but declined to comment further, citing taxpayer confidentiality rules.
Farage has dismissed the Conservative intervention as a politically motivated attack designed to distract from the government's own record. In a statement, a Reform UK spokesman said: «Nigel Farage has fully complied with all legal and tax obligations. This is a desperate attempt by the Conservatives to smear a political opponent because they have no positive message of their own.» The party has not provided detailed documentation of the gift's tax treatment, however, and the matter remains unresolved.
The controversy comes amid broader concerns about the influence of cryptocurrency wealth on British politics. Al Jazeera reported this week that Farage and Reform UK are in «trouble» as the UK braces for the growing role of crypto money in political funding. The report highlighted that Harborne is not the only crypto entrepreneur to have donated to Reform; several other figures from the digital asset sector have also contributed, raising questions about the party's reliance on a largely unregulated industry.
Separately, The Times revealed that a convicted fraudster who previously bankrolled Farage was seen at Reform UK's headquarters. George Cottrell, who served time in a US prison for fraud, was photographed entering the party's offices, prompting further scrutiny of the company Farage keeps. Cottrell had previously been linked to fundraising efforts for Farage's earlier political ventures, and his reappearance has added to the perception that Reform UK's financial networks are poorly policed.
The HMRC investigation request is the latest in a series of challenges facing Farage as he seeks to position Reform UK as a credible alternative to the Conservatives and Labour. The party has enjoyed a surge in opinion polls in recent months, capitalising on voter dissatisfaction with the mainstream parties. However, the growing focus on its funding sources threatens to undermine that momentum, with opponents arguing that Reform UK is too closely tied to opaque offshore money.
Political analysts note that the Conservative move is also a strategic calculation. By targeting Farage's finances, the Tories hope to weaken a rival that is drawing away their traditional voters. The party has been haemorrhaging support to Reform UK, particularly in constituencies where Brexit and immigration remain salient issues. An HMRC investigation, even if it does not lead to a formal penalty, could damage Farage's reputation and slow Reform's rise.
For now, the ball is in HMRC's court. The tax authority has wide discretion over whether to open a formal inquiry, and it may take months or longer to reach a decision. In the meantime, the political fallout is likely to continue, with Farage accusing the Conservatives of using state institutions to harass him, while the Tories insist they are merely upholding tax law. The episode underscores the increasingly bitter rivalry between the two parties on the right of British politics, and the high stakes involved as the next general election approaches.
