City which's announced bid (8)
I believe the answer is:
coventry
'city' is the definition.
(Coventry is an example)
'which's announced bid' is the wordplay.
'which's announced' becomes 'coven' (I can't justify this - if you can you should give a lot more credence to this answer).
'bid' becomes 'try' (I've seen this in other clues).
'coven'+'try'='COVENTRY'
(Other definitions for coventry that I've seen before include "English city" , "cathedral city" , "City devastated in World War II" , "Send to this city to ostracise" , "Where Lady Godiva rode" .)
