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

Newly declassified files reveal the late Queen's very unexpected reaction to the art historian's shocking secret.

Anthony Blunt, who worked at Buckingham Palace as Surveyor of the Queen’s Pictures, was secretly a Soviet spy during WWII.

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

Newly declassified British documents show that Queen Elizabeth II wasn’t told details of her long-time art adviser's double life as a Soviet spy because palace officials didn’t want to add to her worries.

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.

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.
