MIA

Does anyone know if there is a list of missing British and Commonweath service men from WW1 & WW2 ? and / or is there a listing of missing POW’s
ie; those who were known to have been captured but then went missing?

I know that this is available online for American MIA’s but havent found anything for the British, commonwealth or other nationalities who are missing while serving with their forces.

any help would be gratefully accepted.
