A news broadcast with right to reply (6)
I believe the answer is:
answer
'to reply' is the definition.
('answer' can be a synonym of 'reply')
'a news broadcast with right' is the wordplay.
'broadcast with' indicates an anagram (letters scattered or cast around).
'right' becomes 'r' (abbreviation).
'news' anagrammed with 'r' can make 'nswer'.
'a'+'nswer'='ANSWER'
(Other definitions for answer that I've seen before include "It could give you a" , "Fulfil" , "Response to a question" , "Be satisfactory" , "Serve" .)
