City on the Aire (5)
I believe the answer is:
leeds
'city on the aire' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for leeds that I've seen before include "City near Bradford" , "British city and premier division football club" , "City of northern England - castle of southern England" , "Yorkshire city - Kent castle" , "City on River Aire" .)
