MI5 Spied on NHS Founder Bevan for Three Decades, Documents Reveal

• Aneurin 'Nye' Bevan, the founder of the NHS, was monitored by MI5 for over 30 years.
• MI5's surveillance began in the 1930s due to Bevan's links with the Communist Party and his criticism of the British government during World War Two.
• Despite the extensive monitoring, Bevan's personal security file was described as'remarkably tame'.
• The surveillance was based on concerns about Bevan's political affiliations and activities.
• The monitoring continued for over three decades, ending only after Bevan's death.
