People from terrible regimes? (7)
I believe the answer is:
emigres
'people' is the definition.
(emigre is a kind of person)
'terrible regimes?' is the wordplay.
'terrible' is an anagram indicator.
'regimes' with letters rearranged gives 'EMIGRES'.
'from' acts as a link.
(Other definitions for emigres that I've seen before include "People moving to another country" , "People who leave one country to settle in another" , "They may take flight" , "Those leaving their own country for political reasons" .)
