[holding answer 1 March 2007]: The surviving cache of War Office Directorate of Military Intelligence Liberated Prisoner of War Interrogation Questionnaires totalling more than 400 boxes was transferred to The National Archives (TNA) in 2004 into TNA class WO344. No information from these questionnaires remains closed in MOD.
Where allied prisoners of war reported that they had witnessed or obtained information about war crimes, supplementary questionnaires might have been completed. These ‘Form Q’ questionnaires were often passed to war crime investigation units, and surviving files copies may be at TNA in classes WO235, WO309, WO310, WO311 and WO325.
In recent months around 500 files covering World War II war crime investigation have been transferred by MOD to TNA with another, final, transfer of 600 files due in the next few months. These files are known to contain a small number of “Q” questionnaires linked to specific war crime investigations.
