Exile from a corrupt regime (6)
I believe the answer is:
emigre
'exile' is the definition.
(I've seen this before)
'a corrupt regime' is the wordplay.
'a corrupt' indicates an anagram.
'regime' anagrammed gives 'EMIGRE'.
'from' is the link.
(Other definitions for emigre that I've seen before include "One who's fled abroad" , "Person forced to flee his country for political reasons" , "Citizen who has left native country" , "One living abroad for political reasons" , "one who's left" .)
