Correct urge to capture province (6)
I believe the answer is:
punish
'correct' is the definition.
(thesaurus)
'urge to capture province' is the wordplay.
'urge' becomes 'push' (pushing is a kind of urging).
'to capture' is an insertion indicator.
'province' becomes 'NI' (short for Northern Ireland, a province of the UK).
'push' placed around 'ni' is 'PUNISH'.
(Other definitions for punish that I've seen before include "beat" , "Possibly fine" , "Castigate" , "Like wordplay in speech" , "Fine maybe" .)
