You're welcome to a news broadcast (2,5)
I believe the answer is:
no sweat
'you're welcome' is the definition.
I know nothing about this answer so I cannot tell whether it can be defined by this definition.
'to a news broadcast' is the wordplay.
'broadcast' indicates anagramming the letters (letters scattered or cast around).
'to'+'a'+'news'='toanews'
'toanews' anagrammed gives 'NO SWEAT'.
Can you help me to learn more?
(Other definitions for no sweat that I've seen before include "easily done" , "East won (anag)" , "There shouldn't be any objection" , "Not a problem! (informal)" , "fine" .)
