Deputy leader pens directive with a new order (4-9)
I believe the answer is:
vice president
'deputy leader' is the definition.
(I know that vice president is a type of deputy leader)
'pens directive with a new order' is the wordplay.
'with a new order' indicates anagramming the letters (letters in a new order).
'pens'+'directive'='pensdirective'
'pensdirective' with letters rearranged gives 'VICE-PRESIDENT'.
(Other definitions for vice president that I've seen before include "who assists the top man?" , "Not in charge" , "senior politician" , "Second-in-command" , "Number two to 46, say" .)
