City guides, say (5)
I believe the answer is:
leeds
'city' is the definition.
(city in England)
'guides say' is the wordplay.
'guides' becomes 'leads' ('lead' can be a synonym of 'guide').
'say' indicates a 'sounds like' (homophone) clue.
'leads' is a homophone of 'LEEDS'.
(Other definitions for leeds that I've seen before include "Northern town" , "English city" , "City of northern England - castle of southern England" , "City near Bradford" , "West Yorkshire city" .)
