Work against producing token performance (10)
I believe the answer is:
counteract
'work against' is the definition.
(I've seen this in another clue)
'token performance' is the wordplay.
'token' becomes 'counter' (I've seen this in other clues).
'performance' becomes 'act' (act is a kind of performance).
'counter'+'act'='COUNTERACT'
'producing' acts as a link.
(Other definitions for counteract that I've seen before include "Oppose" , "Work against" , "Tell against (something)" , "Take steps to neutralise" , "Nullify" .)
