Riyal spender (5)
I believe the answer is:
saudi
'riyal spender' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for saudi that I've seen before include "Native of Riyadh, possibly" , "One from Riyadh" , "Native of kingdom" , "from the Middle East" , "Native of Riyadh, perhaps" .)
