City article held back for broadcast (8)
I believe the answer is:
adelaide
'city' is the definition.
(I know that Adelaide is or was a state capital)
'held back for broadcast' is the wordplay.
'held' becomes 'adel' (I can't explain this - if you can you should believe this answer much more).
'back' becomes 'aid' (I've seen this in another clue).
'for broadcast' indicates a 'sounds like' (homophone) clue.
'aid' is a homophone of 'aide'.
'adel'+'aide'='ADELAIDE'
'article' is the link.
This may not be right. It may belong to another bit of the clue.
Can you help me to learn more?
(Other definitions for adelaide that I've seen before include "Queen to William IV - setting for many an 6 test" , "Australian location" , "town" , "Lead aide to Oz" , "Commonwealth city" .)
