Socialists admitting fighting to get payments deserved? (7)
I believe the answer is:
rewards
'payments deserved?' is the definition.
'socialists admitting fighting' is the wordplay.
'socialists' becomes 'reds' (red is a kind of socialist).
'admitting' indicates putting letters inside.
'fighting' becomes 'war'.
'reds' enclosing 'war' is 'REWARDS'.
'to get' is the link.
(Other definitions for rewards that I've seen before include "Prizes or remunerations" , "Gifts given in acknowledgement of behaviour or merits" , "Recompenses" , "Honours or shows of appreciation" , "Benefits" .)
