Quick Summary

Nye Bevan, the founder of the National Health Service and a prominent Labour politician, was monitored by MI5 for over two decades due to suspicions of Soviet sympathies. The surveillance began in the 1930s when Bevan was seen as a left-wing backbencher with ties to communists, and continued until at least 1954 despite his public anti-Soviet remarks. Additionally, the article details how another Labour MP, William Owen, was exposed as a Soviet spy who sold defense secrets to Czechoslovakia over a period of 16 years.

Story summary

Aneurin "Nye" Bevan, the Welsh Labour politician known as the "father of the NHS," was monitored by MI5 for over two decades from the early 1930s until his death in 1960, according to recently declassified documents released by the National Archives. Despite concerns about his links with communists and a Russian spy, MI5 files describe Bevan's security dossier as "remarkably tame." The agency never intercepted Bevan’s mail or tapped his phone, and some officers questioned why he was under scrutiny given that his parliamentary statements were often similar to those in public records like Hansard. Bevan came to prominence during World War II as a vocal critic of the government and continued to be monitored even after becoming Minister for Health in 1948 and establishing the NHS.
