UK Tightens Election Funding Rules on Crypto Billionaire Donors
In brief
- UK extends £100,000 overseas donation cap to cover donor's first year of residency
- Christopher Harborne, Tether investor, donated £12 million to Reform UK and registered to vote
- BitMEX co-founder Ben Delo contributed ~£4 million to the party
- Reform was only major UK party accepting crypto donations before March ban
Crypto Cash Under Fire
The new rules extend a cap on overseas donations that's been in force since March, preventing donors from simply relocating to the UK and writing larger checks. The government also tightened rules on company donations—now judged on post-tax profits over five years rather than revenue—and requires candidates to prove any pre-campaign funding came from legitimate sources.
The crackdown lands amid mounting scrutiny of Reform's funding model. Reform UK was the only major British political party to accept donations made in cryptocurrency at the time of the March ban. The broader regulatory package banned crypto donations entirely until the UK can regulate them properly.
Undeclared Gifts and Offshore Casinos
Nigel Farage is already under investigation over an undeclared £5 million gift from Harborne. A Sunday Times investigation alleged that Farage failed to declare years of in-kind help from George Cottrell, a convicted fraudster and crypto-gambler who pleaded guilty to wire fraud in the U.S. after a 2016 sting. Cottrell became a key player in Tether.bet, an offshore casino that took bets in cash or crypto and operated without a UK gambling licence.
Farage denies that benefits from Cottrell needed declaring, and Cottrell denies having expected anything in return. Liberal Democrat MP Josh Babarinde has written to the Parliamentary Standards Commissioner calling for an investigation into Farage's failure to declare financial support from Cottrell.
Pardon and Precedent
Ben Delo was pardoned by U.S. President Donald Trump in 2025 after pleading guilty to violations of the Bank Secrecy Act. His involvement in Reform's funding, combined with Harborne's recent voter registration and the scale of both men's donations, prompted the government to act. The new residency rule closes a loophole that allowed wealthy overseas donors to front-load contributions upon moving to Britain.
