Edward Ledger (5)
I believe the answer is:
heath
I believe this clue is a double definition.
'edward' is the first definition.
(Edward Heath, UK prime minister 1970-1974)
'ledger' is the second definition.
(actor Heath Ledger)
(Other definitions for heath that I've seen before include "See 16" , "Moor" , "Sir Edward - , PM" , "Barren open country" , "Shrubby area of open country" .)
