Rubbish record embarrassed Italian (9)
I believe the answer is:
discredit
'rubbish' is the definition.
(rubbish can mean to discredit or deny)
'record embarrassed italian' is the wordplay.
'record' becomes 'disc' (synonyms).
'embarrassed' becomes 'red' (someone may blush or go red when embarrassed).
'italian' becomes 'it' (abbreviation for Italian).
'disc'+'red'+'it'='DISCREDIT'
(Other definitions for discredit that I've seen before include "To tarnish" , "bad reputation" , "damage to good name" , "Damage reputation of, cause to be disbelieved" , "Rubbish" .)
