MI5: Official Secrets

Spy fiction has captivated our imagination for decades, but the truth behind Britain's security service is even more fascinating than the high-stakes capers of the movies. At The National Archives, we hold the real files—declassified documents that reveal the actual operations, successes, and sometimes failures of MI5 since its creation in 1909. 

In celebration of our new exhibition featuring these secret files and spy gadgets, this episode delves into the real world of espionage – one perhaps more intriguing than fiction. 

Our guests include Gill Bennett, a historian specialising in secret intelligence and former Chief Historian at the Foreign Office, and Mark Dunton, Principal Records Specialist at The National Archives.
