Deny litter producer's implicated in racket (6)
I believe the answer is:
disown
'deny' is the definition.
(I've seen this before)
'litter producer's implicated in racket' is the wordplay.
'litter producer' becomes 'sow' (I've seen this in another clue).
'implicated in' is an insertion indicator.
'racket' becomes 'din' (both can mean a loud noise or disturbance).
'sow' placed inside 'din' is 'DISOWN'.
(Other definitions for disown that I've seen before include "Refuse to be associated with (something/someone)" , "Repudiate, disclaim" , "Refuse to be associated with (a person)" , "Reject all connection with, refuse to acknowledge" , "Wins do (anag)" .)
