Exiled or left, in fact (8)
I believe the answer is:
deported
'exiled' is the definition.
('deport' can be a synonym of 'exile')
'left in fact' is the wordplay.
'left' becomes 'port' (left side of a ship - opposite of starboard).
'in' indicates putting letters inside.
'fact' becomes 'deed'.
'port' going inside 'deed' is 'DEPORTED'.
'or' acts as a link.
(Other definitions for deported that I've seen before include "Expelled from a country" , "despatched overseas" , "sent overseas" .)
