|Fox and his boyfriend Werritty|
The self-styled adviser to Mr Fox, whose close personal friendship with the former defence secretary led to Mr Fox's downfall, has visited Iran on several occasions and met Iranian opposition groups in Washington and London over the past few years, The Independent on Sunday has learnt.
Mr Werritty, 33, has been debriefed by MI6 about his travels and is so highly regarded by the Israeli intelligence service Mossad – who thought he was Mr Fox's chief of staff – that he was able to arrange meetings at the highest levels of the Israeli government, multiple sources have told The IoS.
Mr Fox resigned on Friday after a stream of revelations surrounding his dealings with his adviser, centring on 18 meetings abroad at which Mr Werritty was present, including in Dubai, Sri Lanka and Israel, and 22 at the Ministry of Defence. After vowing to fight the disclosures a week ago, Mr Fox quit the Cabinet on Friday when details emerged of the business and intelligence interests of Mr Werritty's financial backers.
The minister admitted that he had allowed the distinction between his personal interests and government activities had become "blurred". But The IoS has learnt that Mr Werritty's travels went further than the luxury hotels of Colombo and Dubai: he has used his House of Commons-branded business card, which said he was Mr Fox's adviser, to pursue his business interests in conflict-torn South Sudan, other developing African countries and Iraq. The aide has also held talks in London with representatives of the new Libyan government in recent weeks. It is not known whether Mr Fox was present.
The fresh disclosures are likely to form part of Sir Gus O'Donnell's inquiry into Mr Fox and Mr Werritty, which was launched last week as the scandal unfolded. The revelation that the man who had unrestricted access to Mr Fox while he was serving in David Cameron's Cabinet was at the same time attempting to unseat the Iranian President will fuel alarm in the Foreign Office that he was pursuing a freelance foreign policy and acting as a "rogue operator".
