Kid taking part in news programmes (5)
I believe the answer is:
sprog
'kid' is the definition.
(I know that sprog is a type of kid)
'part in news programmes' is the wordplay.
'part in' indicates a hidden word.
'SPROG' can be found hidden inside 'news programmes'.
'taking' acts as a link.
(Other definitions for sprog that I've seen before include "Child, colloquially" , "Kid" , "Child; recruit (mil. slang)" , "little one" , "Infant" .)
