Nasty one is come to cut services (9)
I believe the answer is:
economise
'cut services' is the definition.
(I've seen this before)
'nasty one is come' is the wordplay.
'nasty' is an anagram indicator (a nasty or wrong spelling).
'one'+'is'+'come'='oneiscome'
'oneiscome' anagrammed gives 'ECONOMISE'.
'to' is the link.
(Other definitions for economise that I've seen before include "Make savings" , "Keep down costs" , "Cut back on expenses, be thrifty" , "save?" , "cut costs" .)
