• Hans Möhring, an official on the GDR state planning commission, who was released in 1976 when the West German government ransomed him from the GDR for 500,000 Marks. It was reported then that he had spied for Britain and there was media speculation suggesting he was a victim of Blake, but no evidence was offered publicly. The Stasi files seen by Mr Carey proves definitively that Blake exposed Möhring, who was born on March 5, 1917. He was arrested in 1959 and held for 324 days in Hohenschöenhausen, before being sentenced to life imprisonment for conducting "serious espionage" the next year. He served his sentence in Bautzen II, another Stasi facility.
