Special Reports

The majority of the Committee's Special Reports, like its Annual Reports, are made to both the Prime Minister (in classified form) and to Parliament (with sensitive material redacted). However, a small number of reports, which deal with the most highly classified matters, may be made solely to the Prime Minister.
