Notorious spy Kim Philby 'confesses' in new video clip
Revealing new insights into Britain's most infamous spy have finally come to light following the publication of a secret video showing his long-term career as a double agent for the Soviet Union.
In previously unseen footage recovered by the BBC, Kim Philby, the ex-MI6 officer who rose up the ranks of British intelligence before defecting to become a Russian spy, said he regularly passed on top-secret information to his Soviet contacts "year in, year out".
The new footage is taken from a secret lecture given by Philby in 1981, in which he is seen briefing the East German Intelligence Service, the Stasi, about his life as a double-agent.
It is the first time that footage of the former MI6 officer has been released to the public, and reveals Philby talking about his career rising up through the ranks of MI6 while passing on intelligence to Soviet contacts in the KGB.
During the video, discovered at the official archives of the Stasi in Berlin, Philby, who was known during the Cold War as Britain's biggest traitor, warns the audience that he is "no public speaker", adding that he "spent most of my life trying to avoid publicity of any kind".
"You have probably all heard stories that the SIS (Secret Intelligence Service) is an organisation of mythical efficiency, a very, very dangerous thing indeed," he said.
"Well, in a time of war, it honestly was not. Every evening I left the office with a big briefcase full of reports which I had written myself, full of files taken out of the actual documents, out of the actual archives.
"I used to hand them to my Soviet contact in the evening. The next morning I would get the files back, the contents having been photographed, and take them back early in the morning and put the files back in their place. That I did regularly, year in, year out."
Created and archived in the height of secrecy, the new footage is the first and only evidence of Philby admitting that he worked for the KGB.
