Is question on radio about parking in town? (7)
I believe the answer is:
ipswich
'town?' is the definition.
(I've seen this before)
'is question on radio about parking' is the wordplay.
'question on radio' becomes 'wich' (I can't justify this - if you can you should give a lot more credence to this answer).
'about' is an insertion indicator.
'parking' becomes 'p'.
'is'+'wich'='iswich'
'iswich' placed around 'p' is 'IPSWICH'.
'in' is the link.
(Other definitions for ipswich that I've seen before include "Country town of Suffolk" , "Suffolk town on the River Orwell" , "County town of Suffolk" , "9 across town" , "Wolsey's birthplace" .)
