Newly declassified documents reveal that Queen Elizabeth II was unaware for nearly a decade that Anthony Blunt, a senior royal art historian, had confessed to being a Soviet spy. Blunt, part of the Cambridge Five spy ring, admitted to espionage in 1964 after being promised immunity. The queen was officially informed about Blunt's past in 1973, and she reacted calmly. The documents also detail the activities of other members of the Cambridge Five, including Kim Philby, who betrayed a KGB officer. Teljes cikk (Euronews.com)
