Keir Starmer stood up in the House of Commons on Tuesday and took a sledgehammer to Nigel Farage’s funding model. The Prime Minister announced an immediate moratorium on cryptocurrency donations to all UK political parties, citing the Rycroft review’s conclusion that digital assets present an unacceptable risk of hidden foreign money entering British politics.

The ban takes effect immediately and will be backdated to the date of the announcement, though it requires parliamentary approval to become permanent. Alongside the crypto moratorium, Starmer introduced an annual cap of £100,000 on donations from British citizens living abroad — a measure that affects all parties but hits Reform UK hardest.

Why Reform UK is the target

Reform UK is one of the few British political parties that actively solicits and accepts cryptocurrency donations. According to Electoral Commission figures, the party received £12 million in the past year from Christopher Harborne, a British businessman based in Thailand who has made his fortune in crypto and fintech.

Harborne’s donations are legal under current rules — he is a British citizen on the electoral register — but the Rycroft review flagged the “inherent opacity” of cryptocurrency as a vehicle for political funding. The review did not allege wrongdoing by Harborne or Reform UK, but recommended a pause on all crypto donations while regulators develop stricter traceability standards.

Reform walks out

Reform UK lawmakers walked out of the Commons chamber in protest after Starmer’s announcement. Deputy leader Richard Tice accused the government of “trying to stop the incredible progress of Reform” and called the moratorium “a politically motivated attack on democracy itself.”

Farage, who was not in the chamber, posted on social media that Labour was “terrified of Reform and using the machinery of the state to kneecap us financially.” He pledged to challenge the moratorium in court.

The overseas cap

The £100,000 annual cap on overseas donations is less dramatic but potentially more significant in the long term. An estimated 3.5 million British citizens live abroad, many of whom gained the right to vote in UK elections under the Elections Act 2022. The Conservatives had championed overseas voting rights; Labour is now limiting the financial influence that comes with them.

The cap applies to individual donations from overseas-registered voters. It does not affect British citizens resident in the UK or donations from UK-registered companies. Labour says the measure is about protecting the integrity of British democracy. The opposition says it is about rigging the rules to suit the ruling party.

Both things can be true at the same time.
