An anti-Pole - turns out to be Italian (10)
I believe the answer is:
neapolitan
'be italian' is the definition.
(I've seen this before)
'an anti-pole turns out' is the wordplay.
'turns out' indicates anagramming the letters.
'an'+'anti'+'pole'='anantipole'
'anantipole' anagrammed gives 'NEAPOLITAN'.
'to' is the link.
(Other definitions for neapolitan that I've seen before include "Three-coloured ice cream" , "One coming from Campania" , "Italian citizen" , "From Naples" , "Italian native" .)
