The Metropolitan Police is investigating payments made to Reform UK through a company controlled by the party's deputy leader, Richard Tice, following a referral from the Electoral Commission. Detectives from the Met's Special Enquiry Team are examining alleged offences under section 61 of the Political Parties, Elections and Referendums Act 2000, which governs the handling and reporting of political donations (The Guardian).

At the centre of the investigation are two donations of £250,000 each made to Reform UK by Britain Means Business, a company of which Tice is the sole director, in the weeks before the 2024 UK general election. These donations were funded by a £1 million transfer made on 10 June 2024 by Fiona Cottrell to Britain Means Business. Approximately £500,000 of that sum was subsequently passed to Reform UK (The Guardian; The Guardian).

The £1 million transfer was flagged by bankers in a suspicious activity report to the National Crime Agency. Neither the NCA nor the bankers have been able to trace the original source of the funds, and the NCA is now seeking assistance from a foreign partner to establish provenance. Additional Reform UK-related transactions worth millions of pounds, beyond the Cottrell transfer, have also been reported to the NCA (The Guardian; The Guardian).

Fiona Cottrell's son, George Cottrell, is a convicted fraudster with close links to Reform UK leader Nigel Farage. Both Fiona and George Cottrell have been interviewed under criminal caution as part of the Metropolitan Police investigation. Lawyers acting for George Cottrell declined to answer detailed questions from the Guardian (The Guardian; The Guardian).

The scope of the police investigation extends beyond the Britain Means Business route. Fiona Cottrell also made two direct donations of £250,000 each to Reform UK in May 2024, and these are also within the scope of the inquiry. In total, the investigation encompasses at least £1 million in donations linked to Cottrell, split between direct party donations and funds channelled through Tice's company (The Guardian).

The investigation was launched in February 2025 after the Electoral Commission referred donations made to a political party ahead of the 2024 general election. Early investigative advice has been sought from the Crown Prosecution Service. Two people have been interviewed under caution; no arrests have been made (The Guardian).

Richard Tice has publicly responded to the investigation. He said he first learned of the police inquiry from the BBC and accused Met leadership of engaging in a "politically motivated smear campaign against Reform and its leaders" (The Guardian).

The Guardian first revealed the payments now under investigation and has published a series of investigative articles on Reform UK's finances beginning at least as early as 8 July 2026 (The Guardian; The Guardian).

The investigation sits at the intersection of two distinct legal frameworks. Section 61 of the Political Parties, Elections and Referendums Act 2000 criminalises certain conduct related to the concealment or falsification of donations to registered parties, including entering false information in donation records or knowingly furnishing false information about the source of a donation. The NCA's involvement, triggered by suspicious activity reports, falls under anti-money-laundering statutes that require financial institutions to report transactions where the origin or purpose of funds raises concern. The inability of both the NCA and bankers to trace the source of Cottrell's £1 million, and the agency's recourse to a foreign partner, indicate that the provenance question extends beyond UK jurisdiction.

Tice's defence pivots on two claims: that he was unaware of the investigation until contacted by the BBC, and that the inquiry is politically motivated. Neither claim has been substantiated or independently corroborated, and the Met has not publicly responded to the allegation of political bias. The involvement of the Electoral Commission as the referring body, rather than a political opponent, complicates the framing of the investigation as a partisan exercise. The Commission operates independently of government and is statutorily responsible for regulating party finance.

The broader stakes for Reform UK are considerable. The party has positioned itself as an anti-establishment force challenging the integrity of mainstream institutions, and a criminal investigation into its own financial practices, particularly one involving the deputy leader's company, cuts directly against that messaging. The involvement of a convicted fraudster's family in the party's donor base, and the routing of funds through a company controlled by a senior party figure, are the kind of factual patterns that prosecutors and regulators examine for evidence of deliberate circumvention of transparency rules. Whether the CPS will authorise charges is the next decision point, and no timeline has been disclosed.
