Complaint, as Charlie Parker hurriedly withdrew broadcast (4,3)
I believe the answer is:
bird flu
'complaint' is the definition.
(I have seen 'Avian disease' mean 'bird flu' so perhaps 'disease' could also mean 'bird flu')
'charlie parker hurriedly withdrew broadcast' is the wordplay.
'charlie parker' becomes 'bird'.
'hurriedly withdrew' becomes 'flew' (to fly away is to hurriedly run away).
'broadcast' shows a homophone (sound like) (how the word might sound on the radio or TV).
'flew' is a homophone of 'flu'.
'bird'+'flu'='BIRD FLU'
'as' acts as a link.
(Other definitions for bird flu that I've seen before include "Avian virus that can spread to humans" , "Avian disease contractible by humans" , "viral disease" , "Poultry virus that can spread to humans" .)
