City is ahead, reportedly (5)
I believe the answer is:
leeds
'city' is the definition.
(city in England)
'is ahead reportedly' is the wordplay.
'is ahead' becomes 'leads' (I've seen this in another clue).
'reportedly' shows a homophone (sound like).
'leads' sounds like 'LEEDS'.
(Other definitions for leeds that I've seen before include "City near Bradford" , "City of northern England - castle of southern England" , "W Yorkshire city" , "English city" , "City on River Aire" .)
