City centre has developed next to motorway (10)
I believe the answer is:
manchester
'city' is the definition.
(Manchester is an example)
'centre has developed next to motorway' is the wordplay.
'developed' is an anagram indicator.
'next to' means one lot of letters go next to another.
'motorway' becomes 'M' (as in motorway names - M1, M4 etc).
'centre'+'has'='centrehas'
'centrehas' with letters rearranged gives 'anchester'.
'anchester' after 'm' is 'MANCHESTER'.
(Other definitions for manchester that I've seen before include "English city" , "City of the Halle Orch." , "See 22" , "MUFC" , "Airport in north-west England" .)
