Official Secrets is the name of a film released at the end of last year, which tells the true story of Katharine Gun, a GCHQ whistleblower who leaked information to the Observer newspaper about a dirty tricks campaign by US and UK intelligence agencies as they tried to justify invading Iraq. On this episode, we speak with Yvonne Ridley, the journalist who received those secret documents.
