21 Aug 2015 12:25 PM

We have recently made available to the public 102 previously top secret files from the UK Security Service – sometimes known as MI5.

The files reveal much about the activities of Cold War spies, communist sympathisers, the British fascist movement both during and after the Second World War, and other individuals subject to Security Service enquiry between 1926 and 1964.

Some familiar names include:

You will find files on Harold Laski, who was a committee member of the Friends of the Soviet Union in 1936 (KV 2/4078 to 4079). There are also files on Austrian-born Edith Tudor-Hart, who is thought to have first recruited Philby into Soviet intelligence (KV 2/4091 to 4093).

Listen to an introduction to the files by Professor Christopher Andrew, former official historian of MI5, or read more on our blog.
