Administration; authorities (10)
I believe the answer is:
management
This clue is a double definition.
'administration' is the first definition.
(management is a kind of administration)
'authorities' is the second definition.
(thesaurus)
(Other definitions for management that I've seen before include "Business's upper echelons" , "board" , "Administration" , "Organisation's runners" , "Organisation's leaders" .)
