Person associated with Venice, old region in resort (9)
I believe the answer is:
gondolier
'person associated with venice' is the definition.
(gondolas are associated with Venice)
'old region in resort' is the wordplay.
'in resort' indicates an anagram.
'old'+'region'='oldregion'
'oldregion' is an anagram of 'GONDOLIER'.
(Other definitions for gondolier that I've seen before include "Propeller of Venetian boat" , "Craftsman" , "Traditional boatman of Venice" , "Punter" , "to leave Red Lion disorientated" .)
