An ex-MI6 officer who is believed to have prepared memos claiming Russia has compromising material on US President-elect Donald Trump is now in hiding, the BBC understands.
Christopher Steele, who runs a London-based intelligence firm, is believed to have left his home this week.
Mr Steele has been widely named as the author of a series of memos - which have been published as a dossier in some US media - containing extensive allegations about Mr Trump's personal life and his campaign's relationship with the Russian state.
The memos contain unsubstantiated claims that Russian security officials have compromising material on Mr Trump.
Among the allegations are that Moscow has a video recording of Mr Trump with prostitutes and damaging information about his business activities.
As it was reported earlier, American daily Buzzfeed posted a 35-pages report of Russia’s special forces compromising information on US President-elect Donald Trump. The daily referred to a person who has claimed to be a former British intelligence official. The dossier, which is a collection of memos written over a period of months, includes specific, unverified, and potentially unverifiable allegations of contact between Trump aides and Russian operatives, and graphic claims of sexual acts documented by the Russians of Trump when he was in Moscow in 2013. In particular, it claims that Russian security services were recording Trump’s room at the Ritz Carlton, where Trump invited prostitutes.BuzzFeed News reporters in the US and Europe have been investigating various alleged facts in the dossier but have not verified or falsified them.
Later, the president-elect Donald Trump claimed during his first news conference since winning the election that he does not have any financial ties or business with Russia.
