Declassified recording details how double agent Kim Philby betrayed Western intelligence

Historical footage captures British double agent Kim Philby explaining to Stasi officers how he compromised Cold War secrets for the KGB.
Historical accounts highlight the defecting of British double agent Kim Philby, whose flight to the Soviet Union was made public on July 30, 1963. Philby, a high-ranking MI6 officer who secretly spied for the Soviet KGB for nearly two decades, passed critical intelligence from both British and American agencies to Moscow during the Cold War.
Years after escaping to Moscow, Philby delivered a private lecture to officers of the East German Stasi, detailing the methods he used to bypass internal suspicions and evade prosecution. The rare footage of his address offers historical insight into how he exploited institutional trust within British intelligence to carry out one of the most damaging espionage operations of the twentieth century.
