Capital of Corsica (7)
I believe the answer is:
ajaccio
'capital of corsica' is the definition.
(I've seen this before)
This is the entire clue.
(Other definitions for ajaccio that I've seen before include "Corsican town, Napoleon's birthplace" , "Corsican city" , "island port" , "town on the Med" , "Corsican capital" .)
