The Parliamentary Commissioner for Standards, Daniel Greenberg, opened a formal investigation of Nigel Farage on Wednesday 13 May 2026 over an undeclared £5 million personal gift received from Christopher Harborne in early 2024, allegedly in breach of the House of Commons Code of Conduct. 1 Three parallel inquiries now run into the same donor relationship: the Standards Commissioner on declarations, the Electoral Commission on party donations , and the FCA (Financial Conduct Authority) on Farage's promotional role in Stack BTC, in which he held a 6.31 per cent stake worth roughly $286,000 , .
Harborne is the cryptocurrency investor and Tether stakeholder resident in Thailand whose declared Reform donations make him the largest single individual donor on UK political-finance record. His combined footprint, per figures consolidated by the Crypto Times from the Standards Commission filing, runs at roughly £37 million: £10 million to the Brexit Party in 2019, more than £22 million to Reform UK across 2025, and the £5 million personal gift to Farage now under formal investigation.
The Code of Conduct's registration rule sets the legal test. The Code requires registration of any benefit "reasonably perceived as influencing" parliamentary conduct (House of Commons Standards Committee, 12th Edition). Farage and Reform deputy leader Richard Tice have framed the £5 million as an "unconditional personal gift" for lifetime security costs, citing milkshake incidents and a 2025 firebomb attack on Farage's home. Greenberg's predecessors have found in marginal cases that even unconditional gifts can trigger registration where the donor has a continuing political interest; Harborne's £22m to Reform UK is exactly that interest, made operative. The Commissioner will rule on whether the framing meets the Code's declaration test.
The three-regulator overlay creates an unusual forensic environment. If the Standards finding goes against Farage, the FCA's Stack BTC inquiry intersects with it: a gift judged inducement-related becomes a Section 89 of the Financial Services Act test rather than a Code of Conduct one. The Electoral Commission's existing wallet-address inquiry on Reform UK crypto donations is the third axis. Three regulators, one donor, three statutory tests, all running concurrently. The party funded by that donor has just taken 14 councils and 17 Holyrood seats , . The legislation that would have settled the disclosure rules (event 13) was not in the King's Speech.
