Political exile (6)
I believe the answer is:
emigre
'political exile' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for emigre that I've seen before include "settler" , "One who's fled abroad" , "Person settling in another country" , "Political refugee, especially a royalist fleeing the French Revolution" , "Person who settles in another country" .)
