State hates cuts planned in service (13)
I believe the answer is:
massachusetts
'state' is the definition.
(Massachusetts is an example)
'hates cuts planned in service' is the wordplay.
'planned' is an anagram indicator.
'in' is an insertion indicator.
'service' becomes 'mass' (I've seen this in other clues**).
'hates'+'cuts'='hatescuts'
'hatescuts' anagrammed gives 'sachusett'.
'sachusett' inserted into 'mass' is 'MASSACHUSETTS'.
(Other definitions for massachusetts that I've seen before include "US state, capital Boston" , "New England state" , "One of the original 13 US states" , "Harvard's state" , "A NE US state" .)
