Individual flogging stolen gin (9)
I believe the answer is:
singleton
'individual' is the definition.
'flogging stolen gin' is the wordplay.
'flogging' is an anagram indicator.
'stolen'+'gin'='stolengin'
'stolengin' is an anagram of 'SINGLETON'.
(Other definitions for singleton that I've seen before include "Anything on its own" , "Stolen gin (anag.)" , "one without a mate?" , "just one thing" , "Bachelor maybe" .)
