Liberal, radical and socialist with empties all around could be drunk (7)
I believe the answer is:
oloroso
'be drunk' is the definition.
The definition suggests a singular noun which matches the answer.
'liberal radical and socialist with empties all around' is the wordplay.
I cannot quite see how this works, but
'liberal' could be 'l' (abbreviation) and 'l' is present in the answer.
'radical' could be 'r' (chemistry abbreviation) and 'r' is located in the answer.
'empties' could be 'oo' (two O's - O looks like zero) and 'oo' is found in the leftover letters.
'around' could be 'o' (a round letter) and 'o' is found within the answer.
The remaining letters 'so' is a valid word which might be clued in a way I don't see.
This may be the basis of the clue (or it may be nonsense).
'could' acts as a link.
Can you help me to learn more?
(Other definitions for oloroso that I've seen before include "Dark type of sherry" , "Dark, sweet sherry" , "wine" , "Medium-sweet sherry" , "Heavy dark sherry" .)
