Comrade Philby is the fascinating story of a British agent and Oxbridge gent who turned spy for the Russians. Harold Adrian Russell Philby, known to his Muscovite companions as Comrade Kim, defected to the Soviet Union in 1963, working as a British affairs consultant until his death in the late 1980s. He was buried with the military honours normally reserved for a KGB agent.

This gripping documentary investigates the life of a man considered a traitor in his native Britain, but a hero in Russia.
