3. Ray Mawby
Ray Mawby is especially interesting because he wasn’t uncovered until 12 years after his death. He was a known communist, but only because he championed gender equality. People say he was guilty of leaking parliamentary office floor plans to the Czechs, who were then among the Soviet Union.
2. Anthony Blunt
Anthony Blunt is one of the Cambridge Five, who were known to hand over intelligence to the Soviet Union while working for the US military. Even after his secret confession, his espionage continued. They only stopped after being publicly outed by the queen.
