Christopher Harborne, a British-Thai billionaire whose fortune traces back to early cryptocurrency investments and a 12% stake in Tether Limited, has handed Reform UK another £3 million. The donation, made in March 2026, follows the £9 million he gave the party in August 2025, which was itself the largest single donation by a living individual to a UK political party.
To put that in perspective: Harborne has now given Reform UK roughly £12 million in the span of about seven months. His cumulative contributions to the party and its predecessor exceed £22 million, which constitutes approximately two-thirds of the party’s total funding since its creation.
Who is Christopher Harborne
Harborne is not a household name in the UK, partly because he hasn’t lived there for over two decades. He resides in Thailand, though he maintains British citizenship, which makes his donations to UK political parties entirely legal under current rules.
His wealth is valued at £18.2 billion according to the 2026 Sunday Times Rich List, placing him at No. 6 in the country. That fortune stems from a combination of aviation businesses, including Sherriff Global Group and AML Global, and early bets on digital assets, including Bitcoin and Ethereum.
