Diesel I avoided travelling round city (5)
I believe the answer is:
leeds
'city' is the definition.
(Leeds is an example)
'diesel i avoided travelling round' is the wordplay.
'avoided' suggests deleting specific letters.
'travelling round' indicates an anagram.
'diesel' with 'i' taken away is 'desel'.
'desel' with letters rearranged gives 'LEEDS'.
(Other definitions for leeds that I've seen before include "W Yorkshire city" , "Yorks city" , "West Yorkshire city" , "British city and premier division football club" , "City of northern England - castle of southern England" .)
