Conflict about action copy discarded daily? (10)
I believe the answer is:
wastepaper
'discarded daily?' is the definition.
(daily can mean a daily newspaper)
'conflict about action copy' is the wordplay.
'conflict' becomes 'war' (war is a kind of conflict).
'about' is an insertion indicator.
'action' becomes 'step' (step is a kind of action).
'copy' becomes 'ape' (ape can mean to copy or imitate).
'step'+'ape'='stepape'
'war' enclosing 'stepape' is 'WASTEPAPER'.
(Other definitions for wastepaper that I've seen before include "rubbish" , "Office or domestic bin" .)
