§ Mr. Levitt
To ask the Secretary of State for Defence how many of the British servicemen held as prisoners in Auschwitz during the second world war are known to be still alive; and what memorials exist to(a) them and (b) those who were interned in other such camps. 
§ Dr. Moonie
The Ministry of Defence (MOD) does not hold complete information on how many British service men held as prisoners of war during the second world war are still alive.
All of those who lost their lives during the world wars are commemorated through the nation's central memorial, the Cenotaph. The MOD holds no central record of memorials erected at individual sites overseas.
