Orange ute used by retainers (9)
I believe the answer is:
entourage
'retainers' is the definition.
(thesaurus)
'orange ute used' is the wordplay.
'used' is an anagram indicator.
'orange'+'ute'='orangeute'
'orangeute' is an anagram of 'ENTOURAGE'.
'by' is the link.
(Other definitions for entourage that I've seen before include "Group of attendants" , "train" , "Supportive group" , "Ego nature found in accompanying group" , "Retinue, cortege" .)
