In 1889 the first Official Secrets Act was passed creating offences of 'disclosure of information' & 'breach of official trust' It limited & monitored what the public could & should be told Since then a culture of secrecy has flourished As successive governments have been selective about what they choose to share with the public we have been left with a distorted & incomplete understanding not only of the workings of the state but of our nation's culture & its past In this important book Ian Cobain offers a fresh appraisal of some of the key moments in British history since the end of WWII including the measures taken to conceal the existence of Bletchley Park & its successor GCHQ for three decades; the unreported wars fought during the 1960s & 1970s; the hidden links with terrorist cells during the Troubles; the sometimes opaque workings of the criminal justice system; the state's peacetime surveillance techniques; & the convenient loopholes in the Freedom of Information Act Drawing on previously unseen material & rigorous research The History Thieves reveals how a complex bureaucratic machine has grown up around the British state allowing governments to evade accountability & their secrets to be buried
