[UK Liberal Democrats Call for Investigation into Nigel Farage's Conflict of Interest with Stack BTC] The UK Liberal Democrats have written to the Financial Conduct Authority (FCA), requesting an investigation into the relationship between Reform UK leader Nigel Farage and the Bitcoin company Stack BTC. The party questions whether Farage's 6.31% stake in Stack BTC and his appearance in the company's promotional videos violate market regulations and constitute a conflict of interest. Stack BTC recently acquired 37 Bitcoins as company reserves, valued at approximately $2.7 million. The FCA stated that it will review the relevant letter and respond accordingly.
