I have been campaigning for over 30 years for justice for Yvonne Fletcher, who was shot and killed outside the Libyan embassy in 1984 (The 30-year rule documents they don’t want you to see, 7 January). I was with Yvonne when she was shot and my words were the last she heard. Although some papers were released last year, I am especially interested in the report by Anthony Duff, who was ordered by Margaret Thatcher to hold an investigation into the failings of GCHQ, among others, in the death of Yvonne. I understand this report is highly critical of MI5 etc and has been withheld from public view. This document would prove, beyond doubt, that my request for an inquiry into the death of Yvonne and the various roles played by several government departments should be allowed. My repeated requests to date have all been refused. I wonder why?
