Attorney General v Blake: George Blake was a former member of the Secret Intelligence Service (MI6) from 1944 to 1961.  For his employment contract, he had signed an Official Secrets Act 1911 declaration to disclose no information about his work.  It applied after his employment ceased.  In 1951, he became a Soviet agent, thus, being a double agent.  He was discovered in 1961 and the British government imprisoned him in Wormwood Scrubs (HM Prison).  He escaped in 1966 and fled to the Soviet Union.  He wrote a book about it and his secret services work called "No Other Choice".  He received a publishing contract for its release in 1989, with Jonathan Cape Ltd.  The information in the book was no longer confidential.  Blake received advanced payments and was entitled to more.  The Crown brought an action for all the profits he made on the book including those that he had not yet received.

First Chief Directorate: The First Main Directorate (or First Chief Directorate, Russian: Первое главное управление, "Pervoye glavnoye upravleniye") of the Committee for State Security of the USSR (PGU KGB) was the organization responsible for foreign operations and intelligence activities by providing for the training and management of covert agents, intelligence collection administration, and the acquisition of foreign and domestic political, scientific and technical intelligence in the Soviet Union.  The First Chief Directorate was formed within the KGB directorate in 1954, and after the collapse of the Soviet Union was renamed as the Central Intelligence Service and finally the Foreign Intelligence Service (SVR RF).  Although the agency "SVR" restyle in 1991 implies a generic overseas surveillance activity, the primary foreign intelligence service in Russia and the Soviet Union has been the GRU, a military intelligence organization and special operations force shrouded in secrecy, most famed for stealing the blueprints of the atomic bomb during the Manhattan Project and barring entry into its headquarters to anyone, even the leader of the Soviet Union proper, without a formal authentication.

Some of her work is in the National Gallery in London.  Brought up in a family of socialists, she trained in photography at Walter Gropius's Bauhaus in Dessau, and carried her political ideals through her art.  Through her connections with Arnold Deutsch, Tudor-Hart was instrumental in the recruiting of the Cambridge Spy ring which damaged British intelligence from World War II until their discovery in the late 1960s.  She recommended Litzi Friedmann and Kim Philby for recruitment by the KGB and acted as an intermediary for Anthony Blunt and Bob Stewart when the "rezidentura" at the Soviet Embassy in London suspended its operations in February 1940. <ref name="Guardian 21/8/2015">The Guardian", 21 August 2015, "How MI5 failed to expose matriarch of Cambridge spy ring" by Ian Cobain</ref>
