English derby town (5)
I believe the answer is:
epsom
'english derby town' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for epsom that I've seen before include "Mopes around English Derby venue" , "Classic venue" , "Home to the Derby and the Oaks" , "Town with racecourse" , "& 5 Purgative medicine" .)
