Deny I featured in awfully rude tape (9)
I believe the answer is:
repudiate
'deny' is the definition.
(thesaurus)
'i featured in awfully rude tape' is the wordplay.
'featured in' is an insertion indicator.
'awfully' is an anagram indicator.
'rude'+'tape'='rudetape'
'rudetape' with letters rearranged gives 'repudate'.
'i' going within 'repudate' is 'REPUDIATE'.
(Other definitions for repudiate that I've seen before include "Refuse to accept" , "Renounce, disown" , "Reject and refuse to acknowledge" , "Give denial" , "Denounce" .)
