Stitched up in news broadcast? (4)
I believe the answer is:
sewn
'stitched up' is the definition.
(I've seen this before)
'news broadcast?' is the wordplay.
'broadcast?' indicates an anagram (I've seen 'broadcast' mean this).
'news' anagrammed gives 'SEWN'.
'in' acts as a link.
(Other definitions for sewn that I've seen before include "Made as garment" , "done with a needle" , "Fastened with thread" , "Joined by stitching" , "Fastened with stitches" .)
