Shortly to get a French veto (4)
I believe the answer is:
anon
'shortly' is the definition.
(synonyms)
I can't explain the remainder of the clue.
Can you help me to learn more?
(Other definitions for anon that I've seen before include "Soon; unattributed" , "At another time, of old" , "Soon - unknown author (abbr)" , "Not identified by name" , "At another time and with no identity, in short" .)
