Club's chauffeur? (6)
I believe the answer is:
driver
This clue is a double definition.
'club's' is the first definition.
(driver is a kind of club)
'chauffeur?' is the second definition.
(thesaurus)
(Other definitions for driver that I've seen before include "Operator of a motor vehicle" , "chauffeuse" , "Golf club; chauffeur" , "Golf club for long shots" , "Golf-club for a motorist" .)
