Daisy Cooper, Liberal Democrat deputy leader, wrote to Financial Conduct Authority (FCA) chief executive Nikhil Rathi on 14 April 2026 requesting a formal investigation into Nigel Farage's involvement with cryptocurrency firm Stack BTC. 1 Cooper's letter alleges Farage appeared in Stack BTC promotional material claiming a £2 million bitcoin purchase on the firm's behalf while personally holding a £215,000 stake representing roughly 6% of the company, which she argues could constitute market abuse and conflict of interest. The FCA confirmed it would review the letter and respond directly.
This is a personal-finance thread, not a donations story. The FCA's jurisdiction is personal market conduct under financial services law; the Radom Pay wallet problem sitting with the Electoral Commission sits under electoral law. Different regulators, different rulebooks, different evidentiary standards. Both threads now reach into the final three weeks of the campaign, alongside the Christopher Harborne £12m donor record already on the register .
At this stage the FCA has received a letter, not opened an investigation. Cooper's framing is a regulatory request; any finding would come after polling day on 7 May regardless of whether the Authority acts.
