Pamplona's province (7)
I believe the answer is:
navarre
'pamplona's province' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for navarre that I've seen before include "Old Basque kingdom" , "Region of Spain, capital Pamplona" , "Part of Spain" , "territory held by Basques" , "Former Basque kingdom" .)
