The MI5 "interference alert," obtained by CNN on Thursday, said: "We judge that the UFWD is seeking to covertly interfere in UK politics through establishing links with established and aspiring Parliamentarians across the political spectrum." The alert also added that Lee has been facilitating "financial donations to political parties, Parliamentarians, aspiring Parliamentarians and individuals seeking political office in the UK, including facilitating donations to political entities on behalf of foreign nationals."
The UK Company Register lists Lee as a British citizen.
