The last forum of accountability? State secrecy, intelligence and freedom of information in the United Kingdom

The official mechanisms of intelligence oversight and accountability in the United Kingdom are arguably disjointed and ineffective. Thus, informal actors such as journalists, have played a more significant role. In addition, a rise of whistleblowers and leakers, such as Chelsea Manning, have highlighted the importance of online archives as an avenue for accountability. The United Kingdom is legally bound to place official documents on the public record at the National Archives. Sensitive material on intelligence and other security subjects majorly impedes the bulk release of documents. Inevitably, the inclination to 'weed' sensitive material from mundane documents has resulted in a costly declassification process. Evidence suggests that historians successfully investigated these subjects through the use of archives, despite the efforts of officials to obfuscate. This article argues that historians increasingly constitute the last forum of accountability and that routine declassification is an important, but neglected aspect of our machinery of intelligence oversight.
