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