Hero in England, I'm a maverick (7,3)
I believe the answer is:
leading man
'hero' is the definition.
(thesaurus)
'england i'm a maverick' is the wordplay.
'maverick' indicates an anagram.
'england'+'im'+'a'='englandima'
'englandima' with letters rearranged gives 'LEADING MAN'.
'in' is the link.
(Other definitions for leading man that I've seen before include "Principal actor" , "Star" , "Protagonist" , "Chief actor" , "megastar?" .)
