Counsel Victor to cut radio's broadcast (7)
I believe the answer is:
advisor
'counsel' is the definition.
(thesaurus)
'victor to cut radio's broadcast' is the wordplay.
'victor' becomes 'V' (phonetic alphabet: alpha, bravo, charlie etc.).
'to cut' means one lot of letters goes inside another (some letters cut their way into a word).
'broadcast' is an anagram indicator (letters scattered or cast around).
'radios' anagrammed gives 'adisor'.
'v' inserted inside 'adisor' is 'ADVISOR'.
(Other definitions for advisor that I've seen before include "I recommend" , "One giving counsel (O, not E)" , "One recommends" , "one counsels" , "Guide; VI roads (anag.)" .)
