A news broadcast with the right to respond (6)
I believe the answer is:
answer
'respond' is the definition.
(I know that respond can be written as answer)
'a news broadcast with the right' is the wordplay.
'broadcast with' is an anagram indicator (letters scattered or cast around).
'the right' becomes 'r' (common abbreviation).
'news' with its letters anagrammed with 'r' makes 'nswer'.
'a'+'nswer'='ANSWER'
'to' acts as a link.
(Other definitions for answer that I've seen before include "Acknowledge" , "Reply or solution" , "What you need" , "'A soft . . . . . . turneth away wrath'" , "Response - solution" .)
