Went back on editorial following green controversy? (7)
I believe the answer is:
reneged
'went back on' is the definition.
('renege' can be a synonym of 'go back on')
'editorial following green controversy?' is the wordplay.
'editorial' becomes 'ed' (I can't justify this - if you can you should believe this answer much more).
'following' is a charade indicator (letters next to each other).
'controversy?' is an anagram indicator (I've seen 'controversy' mean this).
'green' is an anagram of 'reneg'.
'ed' after 'reneg' is 'RENEGED'.
Can you help me to learn more?
(Other definitions for reneged that I've seen before include "Was a rat" , "Go back on, or revoke in card game" , "Broke a promise" , "Did Welsh" , "Went back on (a promise)" .)
