Conductor's need (5)
I believe the answer is:
baton
'conductor's need' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for baton that I've seen before include "Conductor wields it - or a policeman" , "A conductor wields it - or a policemen" , "Conductor's rod" , "Prohibition" , "Piece of equipment" .)
