Key points
- MI5 first opened a personal file on Aneurin Bevan in 1933 over his links with known communists, and monitoring continued for more than two decades.
- Monitoring continued after Bevan became a minister in the postwar Labour government that created the NHS.
- A 1943 MI5 officer argued the service should not be involved, because Bevan made the same remarks in Parliament that appear in Hansard.

Aneurin “Nye” Bevan, the Welsh Labour firebrand who spearheaded the creation of the NHS, was monitored by Britain’s security services for more than two decades. His personal file, now public, shows MI5 first opened it in 1933 over concerns about his links with known communists. Yet one MI5 officer who reviewed the file after Bevan’s death in 1960 called it “remarkably tame”.
The official files were released to the public and are held by the National Archives, the government body that keeps Britain’s historical public records. The papers show that some people inside the security services were not convinced Bevan deserved their attention at all. Monitoring nonetheless continued for years, including after he became a minister in the postwar Labour government.
Why MI5 Opened a File on an Ebbw Vale MP
MI5 is the UK’s domestic security service. Its job is to protect the country from threats such as espionage, which means spying for a foreign power, and subversion, which means efforts to undermine the state from within. In the 1930s, communism was a major concern for the service, and anyone with close ties to communist circles could attract its interest.
Bevan was a backbench Labour MP for Ebbw Vale in South Wales. He came to MI5’s attention in the 1930s because of concerns about his links with known communists. The service opened a personal file on him in 1933, and that file was kept open for more than twenty years.
The starting point was not a single incident. The papers describe a pattern of association and public argument that officers recorded over time. That matters for ordinary readers because it shows how the state could judge a sitting member of Parliament. A file could be opened on a politician because of who he spoke to and what he argued for, not only because of anything he had done in secret.
Bevan’s Dealings With the Communist Party
The file says Bevan was “in close touch” with Harry Pollitt, who was general secretary of the Communist Party of Great Britain, and with others in the party. One entry described him as having “inherited the evangelical fervour of his Welsh forebears and knows how to use it in the communist cause.”
The file also records a plan by Bevan to organise “workers’ freedom groups” to defend against “capitalists”. For MI5, language about organised groups of this kind was enough to raise questions. The plan was political in nature, not a secret operation, but officers still treated it as worth recording.
The relationship was not smooth. Bevan fell out with communist allies, who complained that he was not interested in workers’ unity and was intent on building “a movement of his own”. By 1936 the two sides had reconciled. Bevan supported an application by the Communist Party to affiliate with the Labour Party, which would have meant the party formally joining Labour as an organisation.
This back-and-forth is important context. It suggests Bevan was a difficult ally to the communists as much as a possible partner. The picture MI5 built was more mixed than a simple story of a hidden communist sympathiser.
A Russian Spy Warning Passed to Attlee
At one point, Bevan’s links to a known Russian spy led the then director general of MI5 to approach the prime minister, Clement Attlee, to warn him. The source material does not name the spy, and the file’s account stops at the warning itself.
Attlee led the Labour government from 1945 to 1951. Bevan served in that government as a minister and was closely associated with the creation of the NHS, the health service that still shapes daily life across Britain. A warning about a senior minister’s contacts was therefore a serious matter for the prime minister.
The papers show that this was not a one-off concern. Security officers kept returning to the question of who Bevan associated with, and why it mattered.
The 1949 Concern Over Wilfred Macartney
The concern grew again in 1949. MI5 became worried about Bevan’s friendship with Wilfred Macartney, who had been convicted of spying for Russia in 1928. By then, Bevan was a government minister, so the service’s interest in a friend of a convicted spy carried particular weight.
The files do not say that Bevan knew of, or took part in, any espionage. What they show is that MI5 treated his friendships as something that a senior minister should be warned about. For a reader today, the distinction is important. Being close to someone with a spy conviction is not the same as being a spy, but in the security services’ view of the period, the connection was still worth tracking.
The 1943 Officer Who Said MI5 Should Stay Out
Not everyone inside the service agreed with this approach. In 1943, one officer wrote: “I do not think that Bevan’s activities are a matter in which we, the Security Service, should be involved.”
The same officer gave a practical reason. “In fact he makes exactly the same remarks in the Houses of Parliament pretty frequently, as any copy of Hansard will show, and it would not therefore be possible to do anything positive.”
Hansard is the official published record of what is said in Parliament. The officer’s point was that Bevan’s views were already on the public record. There was nothing secret to uncover, and nothing the service could act on. In that view, parliamentary speech was open political debate, not a security threat.
It is a notable position for a security officer to record in an official file. It shows an internal disagreement about where the line should sit between watching a politician and interfering with him.
No Phone Taps or Intercepted Post in the Files
The papers are clear on one point. There is nothing in the files to indicate that MI5 ever tapped Bevan’s phone or intercepted his mail. The monitoring, in other words, does not appear to have reached the most intrusive methods.
The difference matters. Watching a person can mean reading public material, keeping notes on associates and collecting reports. Tapping a phone or opening post is a far more serious step, one that directly invades private communication. On the evidence in these files, the surveillance stayed on the lighter side of that line.
That helps explain the verdict that followed. The file was long, but the material in it was not dramatic. Two decades of attention can look excessive even when what was gathered is thin.
Why the “Remarkably Tame” Verdict Matters
After Bevan died in 1960, another MI5 officer reviewed the file. He wrote: “Considering what a controversial character Nye Bevan was, the file is remarkably tame.” The remark shows that, even inside the service, the case looked slight when set against Bevan’s reputation.
This matters because Bevan is remembered as the architect of the NHS. Seeing how the state watched him adds a second layer to that story. The man who helped set up a national health system was also treated by the security services as a potential risk for much of his political life.
For readers, the story is also about how power was checked in the twentieth century. It asks who decides when a politician becomes a security concern, and on what grounds. The 1943 officer thought the answer was simple: if the speech was already public, the service had no business in it. The files show that other officers did not agree, and kept the file open anyway.
The immediate next step is that the papers are now open to historians and the public. Researchers are likely to use them to examine how MI5 judged politicians on the left during the 1930s and 1940s, and how far officers believed their remit should extend. The wider release will also show whether other politicians’ files contain the same mix of caution and concern, which would give a fuller picture of how often elected figures were watched and why.
