Reform UK leader Nigel Farage has stated that two substantial donations totaling £72 million are fully compliant with current legislation, while acknowledging uncertainty about their legality should proposed rule changes be enacted. The government is considering legislation to cap donations from British expatriates at £100,000 annually, with a proposed backdated effective date of March 25, 2026.

These significant contributions, each amounting to £36 million from businessmen Ben Delo and Christopher Harborne, represent the largest sums ever donated to a political party in British history. Both donors are British nationals who have resided abroad until recently. Farage asserted that the donations were unequivocally within the bounds of existing law.

When questioned about the donors' residency status as of the proposed March 25th deadline, Farage declined to provide specific details. He strongly criticized the government's apparent intention to retroactively invalidate donations, arguing that such actions could lead to retaliatory measures. Farage suggested that if his party were in power, they might impose restrictions on trade union donations, a move he believes could destabilize the current system of political financing.

The proposed legislation, currently under debate in the House of Lords, aims to limit donations from Britons living overseas to £100,000 per year. Furthermore, individuals returning to the UK would be required to wait at least one year before making donations exceeding this cap. The legislation specifies that donors must have been registered as residing in the UK by March 25, 2026, to be exempt from the proposed cap.

Education Minister Georgia Gould expressed the government's concern regarding the influence of large sums of money, particularly from overseas, on political discourse. She indicated that the proposed rule changes were incorporated into the Representation of the People Bill following a review by former senior civil servant Sir Philip Rycroft, which focused on foreign interference in British politics and was published on March 25th.

Trade union leader Paul Nowak contrasted the proposed restrictions on expat donations with the contributions made by trade union members. He argued that the regular, smaller contributions from workers through their unions are fundamentally different from donations made by billionaires, suggesting the latter could give the impression of a party being controlled by wealthy individuals.

Since 2020, the Labour Party has reportedly received nearly £43 million from trade unions, with funds primarily sourced from individual membership fees. The substantial donations to Reform UK have re-energized discussions surrounding the transparency and regulation of political funding in the United Kingdom.

It remains unclear at this stage whether Ben Delo and Christopher Harborne had returned to the UK before the March 25, 2026, cut-off date stipulated in the proposed legislation. Sir Philip Rycroft, in comments made on Radio 5 Live, noted that his review did not extend to examining domestic donations, indicating a potential gap in the current scrutiny of political funding.
