Christopher Harborne, a significant investor in Tether, has been named the sixth richest person in the UK with a fortune of £18.2 billion, according to the Sunday Times Rich List 2026. Harborne's wealth is largely attributed to his 12% stake in Tether, valued at approximately $200 billion. This revelation comes as Harborne faces political scrutiny over a £5 million gift to Nigel Farage, which has prompted a Parliamentary Standards Commissioner inquiry. The inquiry, launched on May 15, investigates whether Farage breached the Commons Code of Conduct by not registering the gift, which he claims was for security costs. Harborne, who has donated over £22 million to Reform UK, is also under scrutiny for his connections to the crypto world, including a referral to the Financial Conduct Authority regarding Farage's involvement with Bitcoin treasury firm Stack BTC. The outcome of these investigations could have significant political implications.
