Editor's opinions of our rulers? (7)
I believe the answer is:
leaders
This clue is a double definition.
'editor's opinions' is the first definition.
(leader can mean a piece by a newspaper's editors)
'our rulers?' is the second definition.
(people who rue us)
'of' is the link.
(Other definitions for leaders that I've seen before include "Bosses" , "Top people" , "They take the initiative and direct others" , "People to follow" , "Guides" .)
