Summary
The UK Liberal Democrats have escalated regulatory pressure on Reform UK leader Nigel Farage by formally requesting a Financial Conduct Authority investigation into his cryptocurrency ventures. Deputy leader Daisy Cooper submitted a letter to FCA CEO Nikhil Rathi on April 14, 2026, demanding scrutiny of Farage's dual role as shareholder and public promoter of Stack BTC, a British bitcoin treasury firm.
The controversy centers on a sequence of financial and promotional events. Farage invested £215,000 in Stack BTC through his holding company Thorn In The Side Ltd, acquiring a 6.3% ownership stake. Weeks later, he appeared in an official promotional video announcing that Stack had executed a £2 million bitcoin purchase, which the company described as a "landmark moment" in British politics. Cooper argues this pattern raises serious questions about market conduct, specifically whether Farage's actions constitute attempted market abuse, improper interference in cryptocurrency markets, or conflicts of interest that could harm retail investors. She expressed concern that Farage's statements promoting cryptocurrency lack adequate risk disclosure to his audience.
Cooper's inquiry also invokes comparative international context. She referenced a Bloomberg investigation documenting that US President Donald Trump and his family have generated approximately $1.4 billion from crypto projects during Trump's second term, suggesting Farage may be following a similar playbook of leveraging political influence for personal financial gain. Cooper stated: "This raises real concerns that Nigel Farage could be using the Donald Trump playbook to put his own financial interests above the public good, potentially luring people into high-risk schemes for his own gain."
The investigation request extends beyond Farage's personal holdings. Cooper highlighted that Reform UK received a £9 million donation from Christopher Harborne, a significant Tether investor, at the end of 2025—described as the largest political donation of its kind in UK history. This financial connection, combined with Farage's long-standing advocacy for cryptocurrency policies including a proposed national bitcoin reserve and enabling HMRC to accept crypto for tax payments, raises questions about whether political advocacy is designed to inflate cryptocurrency valuations for personal and party benefit.
Farage's representatives responded that the Stack BTC transaction was executed "on behalf of Stack and not personally," characterizing the event as a standard "photo call." The FCA confirmed receipt of Cooper's request and stated it would review the matter. The case now represents a significant test of regulatory oversight over political figures engaged in cryptocurrency promotion and investment.
