Police eager to resolve conflict (8)
I believe the answer is:
disagree
'conflict' is the definition.
(thesaurus)
'police eager to resolve' is the wordplay.
'police' becomes 'dis' (detective inspectors or DIs).
'to resolve' indicates an anagram (I've seen 'resolved' mean this).
'eager' anagrammed gives 'agree'.
'dis'+'agree'='DISAGREE'
(Other definitions for disagree that I've seen before include "source of conflict" , "Dire ages (anag.)" , "Beg to differ" , "Have conflicting opinions" , "Take issue with, hold different opinion" .)
