Socialist struggle inspired by boozer (6)
I believe the answer is:
soviet
'socialist' is the definition.
(the Soviet Union was a socialist country)
'struggle inspired by boozer' is the wordplay.
'struggle' becomes 'vie' (I've seen this before).
'inspired by' is an insertion indicator.
'boozer' becomes 'sot' (I've seen this before).
'vie' inserted within 'sot' is 'SOVIET'.
(Other definitions for soviet that I've seen before include "Former Russian council" , "Like the USSR" , "National council in former USSR" , "Old Russian council" , "Relating to the USSR" .)
