One who flees from new regime? (6)
I believe the answer is:
emigre
'one who flees' is the definition.
The answer is a person as well as being a singular noun. This is suggested by the definition.
'new regime?' is the wordplay.
'new' indicates an anagram.
'regime' is an anagram of 'EMIGRE'.
'from' acts as a link.
Can you help me to learn more?
(Other definitions for emigre that I've seen before include "One who's fled abroad" , "settler" , "One gone abroad for political reasons" , "One living abroad for political reasons" , "One living in exile" .)
