"The tape is of Kim Philby giving a secret lecture to the Stasi, the East German Intelligence Service, in 1981. It is the first time the ex-MI6 officer can be seen talking about his life as a spy from his recruitment to his escape."
"He describes his career rising up the ranks of MI6 whilst providing its secrets to the Soviet Union's KGB. He ends with advice to the East German spies."
One of the interesting things for me was how he talks about the fact that he got away with a lot because he was from the "posh", ruling, British class.
