Hand over a representative (8)
I believe the answer is:
delegate
I believe this clue is a double definition.
'hand over' is the first definition.
(thesaurus)
'a representative' is the second definition.
(delegate is a kind of representative)
(Other definitions for delegate that I've seen before include "Representative sent to meeting" , "Transfer power to do something" , "Depute" , "Mandate" , "Consign" .)
