For a decade, Queen Elizabeth II lived without knowing that her own art advisor, Anthony Blunt, a trusted man in charge of overseeing the invaluable Royal Collection, was living a double life as a Soviet agent.

"The Queen found her very down to earth, because she refused to have expensive security...and she loved her lack of airs and graces."

Queen Elizabeth II was not officially informed for nearly a decade that Anthony Blunt was a Soviet spy, newly declassified documents reveal.

Declassified documents confirm that the late Queen Elizabeth II of England was not informed until many years later that she had a KGB spy amongst her members of staff. She didn't like him anyway.
