Might they come from unstable regimes? (7)
I believe the answer is:
emigres
'might they come' is the definition.
The definition suggests an adverb but the answer is not.
'unstable regimes?' is the wordplay.
'unstable' indicates an anagram.
'regimes' is an anagram of 'EMIGRES'.
'from' is the link.
Can you help me to learn more?
(Other definitions for emigres that I've seen before include "People who leave one country to settle in another" , "People moving to another country" , "They may take flight" , "Those leaving their own country for political reasons" .)
