The Metropolitan Police are investigating at least £500,000 in donations made to Reform UK by Fiona Cottrell, the mother of a convicted fraudster.The inquiry, which began in February 2025, focuses on potential violations of donation restrictions, including concealing the source of funds or providing false information about donations.Cottrell allegedly made two payments of £250,000 to Reform UK before the 2024 general election, which were recorded by the Electoral Commission.

The investigation, under Section 61 of the Political Parties, Elections and Referendums Act 2000, involves examining whether these donations were improperly sourced.

Nigel Farage, Reform UK's leader, has denied any wrongdoing, while his son George Cottrell, who paid for his staff and security before the election, has faced fraud charges in the US.The Electoral Commission stated it cannot investigate such cases, leaving the matter to the police.The Met confirmed two individuals have been interviewed under caution, but no arrests have been made.The case highlights concerns about transparency in political financing and the legal boundaries of donor disclosures.
