Concerning papers editor controlled (9)
I believe the answer is:
repressed
'controlled' is the definition.
'concerning papers editor' is the wordplay.
'concerning' becomes 're' (both can mean on a particular topic).
'papers' becomes 'press' (the newspaper industry).
'editor' becomes 'ed' (abbreviation).
're'+'press'+'ed'='REPRESSED'
(Other definitions for repressed that I've seen before include "Inhibited" , "withdrawn" , "Kept under control; put down" , "Kept bottled up" , "Checked" .)
