Russian intelligence alleged to have compromising material on Trump, say unverified reports being prepared by western ex-counter-intelligence official

Senator John McCain passed documents to the FBI director, James Comey, last month alleging secret contacts between the Trump campaign and Moscow and that Russian intelligence had personally compromising material on the president-elect himself.

The material, which has been seen by the Guardian, is a series of reports on Trumps relationship with Moscow. They were drawn up by a former western counter-intelligence official , now running as a private consultant. BuzzFeed on Tuesday published the documents, which it told were unverified and potentially unverifiable.

The Guardian has not been able to confirm the veracity of the documents contents, and the Trump team has consistently denied any concealed contacts with the Russian government.

A spokesman for the Russian president, Vladimir Putin, on Wednesday denied Russia has collected compromising information on Trump and dismissed news reports as a complete fabrication and utter nonsense. Dmitry Peskov insisted that the Kremlin does not engage in collecting compromising material.

Trumps transition team did not immediately respond to a request for commentary, but late on Tuesday, Trump tweeted: FAKE NEWS A TOTAL POLITICAL WITCH HUNT! He constructed no direct reference to the allegations.

An official in the US administration who spoke to the Guardian described the source who wrote the intelligence report as consistently dependable, meticulous and well-informed, with a reputation for having extensive Russian contacts.

Some of the reports which are dated from 20 June to 20 October last year also proved to be prescient, predicting events that happened when he was sent.

One report, dated June 2016, claims that the Kremlin has been cultivating, supporting and assisting Trump for at least five years, with the aim of encouraging divides and divisions in western alliance.
