Unworthy, if daring, broadcast (5,3)
I believe the answer is:
infra dig
'unworthy' is the definition.
(I've seen this before)
'if daring broadcast' is the wordplay.
'broadcast' indicates an anagram.
'if'+'daring'='ifdaring'
'ifdaring' anagrammed gives 'INFRA DIG'.
(Other definitions for infra dig that I've seen before include "Beneath oneself (from Latin)" , "Demeaning (Lat. abbr.)" , "Demeaning (Latin)" , "degrading" , "Rigid fan may be lacking in dignity" .)
