City reelects corrupt one in (9)
I believe the answer is:
leicester
'city' is the definition.
(Leicester is an example)
'reelects corrupt one in' is the wordplay.
'corrupt' indicates an anagram.
'one' becomes 'I' (Roman numeral).
'in' means one lot of letters goes inside another.
'reelects' anagrammed gives 'lecester'.
'lecester' going around 'i' is 'LEICESTER'.
(Other definitions for leicester that I've seen before include "City, Robert Dudley" , "Midland city" , "Queen's favourite" , "Cheese; town" , "Central English city; red cheese" .)
