KIM PHILBY: THE MI6 DOUBLE AGENT WHO SPIED FOR RUSSIA
Blunt’s treachery came to light in 1963 when an American acquaintance and fellow communist from his Cambridge days gave the game away to the FBI. Not wanting this shocking story to go public, the British establishment opted to hush things up and give Blunt immunity from prosecution. Public exposure only came much later, in 1979, when Margaret Thatcher named him as a spy in Parliament. Stripped of his knighthood, Blunt died in disgrace in 1983.
