Doctor bused in to provide media-friendly comment (5,4)
I believe the answer is:
sound bite
'media-friendly comment' is the definition.
(comment designed to be repeated in the media)
'doctor bused in to' is the wordplay.
'doctor' indicates an anagram.
'bused'+'in'+'to'='busedinto'
'busedinto' with letters rearranged gives 'SOUND BITE'.
'provide' is the link.
(Other definitions for sound bite that I've seen before include "Newsworthy quote" , "Pithy extract from something said" , "No subedit for short snappy extract from speech as on TV" , "Short excerpt" , "brief comment heard on the news?" .)
