MI5 amassed hundreds of records on Eric Hobsbawm and Christopher Hill, two of Britain’s leading historians who were both once members of the Communist party, secret files have revealed.
The scholars were subjected to persistent surveillance for decades as MI5 and police special branch officers tapped and recorded their telephone calls, intercepted their private correspondence and monitored their contacts, the files show. Some of the surveillance gave MI5 more details about their targets’ personal lives than any threat to national security.
The files, released at the National Archives on Friday, reveal the extent to which MI5, including its most senior officers, secretly kept tabs on the personal and professional activities of communists and suspected communists, a task it began before the cold war. The papers also show that MI5 opened personal files on the popular Oxford historian AJP Taylor, the writer Iris Murdoch, and the moral philosopher Mary Warnock after they and Hill signed a letter supporting a march against the nuclear bomb in 1959.
