Andrew Lownie recounts how he became the victim of state surveillance as a result of his successful efforts to secure the release of the personal diaries and letters of Dickie and Edwina Mountbatten – bought by the University of Southampton with public funds to be open to researchers – in what became the largest-ever release of material under Freedom of Information (FOI), 33,000 pages, but which personally cost him over £400,000 in legal fees. Drawing on his own research experiences, he also describes the failure of government departments to deposit records at the National Archives as required by statute, the techniques public authorities use to frustrate FOI requests and suggests how FOI could be improved. All of this curation, he argues, leads to a distortion of the historical record and the censoring of our history.
