Dicky is one come to cut services (9)
I believe the answer is:
economise
'cut services' is the definition.
(I've seen this before)
'dicky is one come' is the wordplay.
'dicky' indicates an anagram (dicky can mean ill or non-functioning).
'is'+'one'+'come'='isonecome'
'isonecome' with letters rearranged gives 'ECONOMISE'.
'to' acts as a link.
(Other definitions for economise that I've seen before include "Scrimp" , "Keep down costs" , "Make savings" , "cut services" , "Cut back on expenses, be thrifty" .)
