Biased broadcast? Indeed so! (3-5)
I believe the answer is:
one-sided
'biased' is the definition.
(thesaurus)
'broadcast? indeed so' is the wordplay.
'broadcast?' is an anagram indicator (letters scattered or cast around).
'indeed'+'so'='indeedso'
'indeedso' with letters rearranged gives 'ONE-SIDED'.
(Other definitions for one-sided that I've seen before include "Unfair or partisan - single dimension?" , "Partial" , "So denied being unfair or biased" , "Unbalanced" , "Unfair, unequal" .)
