Introduction

On 7 May 2026 the United Kingdom announced a comprehensive overhaul of its political financing rules. The primary goal is to prevent foreign money from shaping domestic elections, a concern highlighted by Housing Minister Steve Reed as a fight against "dodgy funding."

Key Changes to Donation Limits

Under the new proposals, individuals who have recently moved to the UK will be restricted to a maximum of £100,000 in political donations per year. A minimum period of residence must be met before they can exceed this cap, targeting high‑profile donors such as British billionaire Christopher Harborne, who previously contributed £9 million to the Reform party and additional sums in 2025 and 2023. Cryptocurrency donor Ben Delo, who gave £4 million to Reform in early 2024, will also be subject to the new limits.

Reform of Company Contributions

Corporate donations will no longer be judged solely on revenue; instead, they will be evaluated against post‑tax profits over the preceding five years. This ensures that only financially robust, UK‑linked businesses can support political parties.

Candidate Transparency Requirements

Anyone standing for election must now provide proof that all pre‑candidacy funding originates from legitimate sources. Additionally, candidates are required to declare any donation exceeding £2,230 received before officially becoming a candidate.

Legislative Process and Wider Context

The amendments will be incorporated into the Representation of the People Bill, slated to return to the House of Commons for further debate on 14 July. The reforms are part of a broader response to a review led by former civil servant Philip Rycroft, initiated after concerns about foreign state attempts to meddle in British democracy. Earlier in March, the government also banned cryptocurrency donations and reinstated a £100,000 cap for British citizens living abroad.

Reactions and Outlook

The ruling party praised the measures as world‑leading steps to protect electoral integrity. Critics, including the Reform party, argue that the changes could "choke off legal funding" for opposition groups. Nonetheless, the reforms signal a decisive move toward greater transparency and resilience against external influences in UK politics.
