Broadcast trailed 'Like a Virgin' (6)
I believe the answer is:
chaste
'like a virgin' is the definition.
(I've seen this in another clue)
'broadcast trailed' is the wordplay.
'broadcast' indicates a 'sounds like' (homophone) clue (how the word might sound on the radio or TV).
'trailed' becomes 'chased' ('chase' can be a synonym of 'trail').
'chased' sounds like 'CHASTE'.
(Other definitions for chaste that I've seen before include "Pure and inviolate" , "Morally pure" , "Sachet (anag)" , "Unsullied" , "Modest and virtuous" .)
