Leading intelligence and security expert Gordon Corera discusses The Spy in the Archive – the remarkable story of how the unassuming archivist Vasili Mitrokhin turned KGB traitor when he decided to steal secret Soviet archives and smuggle them to the West.  In conversation with Libby Spurrier, Gordon explains how Mitrokhin had access to extensive intelligence files and why he copied and shared Russia’s secrets.  Gordon has written widely on intelligence issues; he co-hosts the popular ‘The Rest is Classified’ podcast and is a Security Correspondent for BBC News.
