According to The Block, Daisy Cooper, Deputy Leader of the UK Liberal Democrats, has written to Nikhil Rathi, CEO of the UK Financial Conduct Authority (FCA), requesting an investigation into whether Reform UK leader Nigel Farage has any conflicts of interest related to cryptocurrencies. Cooper pointed out that Farage, before participating in a promotional video for Stack BTC and "representing the company in" a £2 million Bitcoin purchase, had invested approximately £215k in the company several weeks prior. She believes that this kind of arrangement—"investing while promoting, then participating in coin purchases"—may involve market abuse risks and could mislead or harm retail investors. Cooper also mentioned that Farage has long publicly supported expanding cryptocurrency use, including proposing the establishment of a "Bitcoin reserve fund" and pushing for the UK tax authorities to accept crypto assets for tax payments.
