Evacuated estate in Mormon city (5)
I believe the answer is:
leeds
'city' is the definition.
(city in England)
'evacuated estate in mormon' is the wordplay.
'evacuated' says to hollow out the word (remove centre letters) (internal letters are evacuated from the word).
'estate' becomes 'life estate' (life estate is a kind of estate).
'in mormon' becomes 'eds' (I can't justify this - if you can you should give a lot more credence to this answer).
'life' with its centre taken out is 'le'.
'le'+'eds'='LEEDS'
(Other definitions for leeds that I've seen before include "English city" , "City near Bradford" , "22 [FA CUP] runners-up" , "Industrial city of northern England" , "Yorkshire city - Kent castle" .)
