Declassified files reveal MI5 monitored NHS founder Nye Bevan for 30 years
British intelligence kept surveillance on Nye Bevan, the creator of the NHS, from 1933 until his death in 1960, according to newly released MI5 documents.
Declassified MI5 records released by the National Archives confirm that Nye Bevan, credited with founding the National Health Service in 1948, was under continuous surveillance from 1933 until he died in 1960. Authorities justified the monitoring by citing his strong socialist stance, criticism of Winston Churchill’s wartime coalition, and suspected ties to the Communist Party. The agency logged his parliamentary activities, personal movements and meetings, yet a 1955 memorandum noted that attempts by the Communist Party and Trotskyists to enlist him had failed.
A post-mortem review of the case described the file as "remarkably tame" despite Bevan’s polarising legacy. The release also included unrelated MI5 files on German diplomat Wolfgang zu Putlitz and Soviet spy Frank Bossard. These revelations highlight the extent of Cold-War era domestic intelligence scrutiny of prominent political figures.
Why it matters
The disclosures show how British security services monitored a key architect of the NHS, shedding light on historic state surveillance practices.
