Breaking news stitched together (4)
I believe the answer is:
sewn
'stitched together' is the definition.
(I've seen this in another clue)
'breaking news' is the wordplay.
'breaking' is an anagram indicator.
'news' anagrammed gives 'SEWN'.
(Other definitions for sewn that I've seen before include "Joined with stitches" , "Run up" , "Fastened with thread" , "Fastened with stitches" , "Fastened with needlework" .)
