Cunning hero wins Portugal title (9)
I believe the answer is:
ownership
'title' is the definition.
(legal term for ownership)
'cunning hero wins portugal' is the wordplay.
'cunning' is an anagram indicator.
'portugal' becomes 'p'.
'hero'+'wins'='herowins'
'herowins' anagrammed gives 'ownershi'.
'ownershi'+'p'='OWNERSHIP'
(Other definitions for ownership that I've seen before include "Proprietary right of possession" , "The right of possessing something" , "Proprietorship, possession" , "Legal title" .)
