We look at how journalists get their hands on declassified documents, and how the release of these files can inform us about the true workings of government. BBC correspondent Sanchia Berg and Phil Tinline, a producer of historical documentaries for the BBC, tell us about some of the memorable documents they’ve come across, and how perusing the archives can offer valuable insight into the events of the past.
