Condemned left-winger embracing what's wrong (7)
I believe the answer is:
reviled
'condemned' is the definition.
(revile means to condemn or criticise)
'left-winger embracing what's wrong' is the wordplay.
'left-winger' becomes 'red' (red can mean a leftwing person).
'embracing' is an insertion indicator.
'what's wrong' becomes 'evil' (associated in meaning).
'red' placed around 'evil' is 'REVILED'.
(Other definitions for reviled that I've seen before include "Deliver (anag.)" , "Abused" , "Maligned, vilified" , "Abusively criticised" .)
