Concerns were raised following a £9m donation to Reform UK from Thai-based crypto billionaire Christopher Harborne, the largest ever political donation by a single living person.
Nigel Farage publicly promoted Tether, a cryptocurrency in which Mr Harborne holds shares, shortly after the donation, leading to accusations of a potential conflict of interest and abuse of his public position.
Mr Farage previously announced that Reform UK would accept crypto donations and has advocated for crypto deregulation, claiming the party had already received 'a couple' of crypto assets.
The Electoral Commission states that no political party has registered crypto assets as donations.
