Supervised section of interview as revolutionary turned up (7)
I believe the answer is:
oversaw
'supervised' is the definition.
('oversee' can be a synonym of 'supervise')
'section of interview as revolutionary turned up' is the wordplay.
'section of' says the answer is hidden in the clue.
'turned up' says the letters should be written backwards.
'wasrevo' is hidden in the letters of 'interview as revolutionary'.
'wasrevo' written backwards gives 'OVERSAW'.
(Other definitions for oversaw that I've seen before include "watcher" , "Supervised" , "Managed" , "What supervisor did" .)
