I attend broadcast that's corrupt (7)
I believe the answer is:
tainted
'that's corrupt' is the definition.
(synonyms)
'i attend broadcast' is the wordplay.
'broadcast' indicates anagramming the letters (letters scattered or cast around).
'i'+'attend'='iattend'
'iattend' is an anagram of 'TAINTED'.
(Other definitions for tainted that I've seen before include "corrupt" , "Flawed, contaminated" , "Spoiled, stained" , "Corrupted, sullied" , "Adulterated" .)
