Editorial guide (6)
I believe the answer is:
leader
This clue is a double definition.
'editorial' is the first definition.
(thesaurus)
'guide' is the second definition.
(thesaurus)
(Other definitions for leader that I've seen before include "Head (of government, etc)" , "Opinion piece; boss" , "Principal first violinist" , "Commander; article" , "Director, guide" .)
