 Also in May 2009, Charles Haddon-Cave, QC, leading the Nimrod Review issued a number of Salmon letters to organisations and senior RAF officers warning them they were likely to be criticised in its formal report.The so-called Salmon letters give those who are likely to be criticised by the inquiry the opportunity to respond to the criticism before the report's publication.The MoD and the Nimrod inquiry team declined to say which senior RAF officers received letters.
