The Conservative Party has called on HM Revenue and Customs to investigate whether Nigel Farage, leader of the Reform Party, owes tax on a £5 million gift he received from the crypto billionaire Christopher Harborne. The party chair, Kevin Hollinrake, wrote to the tax authority questioning whether the payment was in fact compensation for Farage’s decision to stand as a candidate in the general election, which could make it subject to income tax.

The development marks a significant escalation in political tensions between the Conservatives and Reform, as both parties compete for voters ahead of the next election. The Tories have seized on the issue to question the financial arrangements of their rivals, while Reform has dismissed the complaint as a political stunt.

According to the letter sent by Hollinrake, the Conservatives want HMRC to determine whether the £5 million payment from Harborne, a British-born cryptocurrency entrepreneur based in Thailand, was a genuine gift or a payment linked to Farage’s political activities. Under UK tax law, gifts are generally not taxable, but payments for services, including political work, may be subject to income tax and national insurance contributions.

The controversy comes amid broader scrutiny of the role of cryptocurrency wealth in British politics. Harborne, who made his fortune through digital currency trading and blockchain ventures, has been a prominent donor to Reform and other political causes. His financial backing of Farage has drawn attention from regulators and campaigners concerned about the influence of opaque digital fortunes on the democratic process.

Farage has defended the payment, stating that it was a personal gift from a friend and supporter, and that he has complied with all relevant tax rules. His spokesperson said that the Conservative complaint was a desperate attempt to distract from the party’s own problems and that Farage had nothing to hide. The Reform leader has not yet commented publicly on the HMRC inquiry request.

The timing of the Conservative move is notable, coming just days after reports that a convicted fraudster who previously bankrolled Farage was seen at Reform headquarters. The Times reported that George Cottrell, who served a prison sentence for fraud, was spotted visiting the party’s offices, raising further questions about the sources of funding for Reform. Cottrell’s presence has been denied by the party, but the incident has added to the narrative of financial opacity surrounding Farage’s political operation.

Al Jazeera has also reported that Farage and Reform are in ‘trouble’ as the UK braces for the growing influence of cryptocurrency in politics. The report highlighted concerns that unregulated digital wealth could be used to bypass traditional campaign finance rules, potentially distorting the political landscape. The issue has become a talking point among lawmakers, with some calling for tighter controls on donations from crypto-related sources.

The HMRC investigation request is likely to put pressure on Farage to disclose more details about his financial affairs. If the tax authority decides to open a formal inquiry, it could lead to a protracted legal battle and further damage the reputation of the Reform Party, which has positioned itself as an anti-establishment force. The Conservatives, meanwhile, hope that the controversy will undermine Farage’s appeal among voters who are concerned about integrity in politics.

Political analysts note that the dispute reflects the increasingly bitter rivalry between the two right-of-centre parties. The Conservatives have lost significant support to Reform in recent opinion polls, and the party is looking for ways to regain ground. By targeting Farage personally, the Tories may be trying to paint him as part of a political elite that he claims to oppose.

For now, HMRC has not confirmed whether it will act on the Conservative request. The tax authority typically does not comment on individual cases. However, the matter is likely to remain in the public eye as the political battle intensifies. Farage’s response and any further revelations about his financial ties to Harborne will be closely watched by both supporters and critics.
