Pink gin ordered for an important person (7)
I believe the answer is:
kingpin
'for an important person' is the definition.
(kingpin is a kind of important person)
'pink gin ordered' is the wordplay.
'ordered' is an anagram indicator.
'pink'+'gin'='pinkgin'
'pinkgin' with letters rearranged gives 'KINGPIN'.
(Other definitions for kingpin that I've seen before include "Most important member of organisation" , "Main bolt" , "VIP" , "Essential person or thing" , "person with vital role" .)
