Rubbish prize reported in broadcast (8)
I believe the answer is:
disperse
'broadcast' is the definition.
(I know that broadcast can be written as disperse)
I can't explain the remainder of the clue.
(Other definitions for disperse that I've seen before include "'Break up, spread out (8)'" , "Scatter in all directions" , "Scatter, dissipate" , "Presides so as to scatter" , "Scatter, dispel" .)
