Opinion piece from real idiot possibly (9)
I believe the answer is:
editorial
'opinion piece' is the definition.
(I've seen this in another clue)
'real idiot possibly' is the wordplay.
'possibly' indicates anagramming the letters.
'real'+'idiot'='realidiot'
'realidiot' with letters rearranged gives 'EDITORIAL'.
'from' is the link.
(Other definitions for editorial that I've seen before include "Newspaper opinion piece" , "Newspaper article giving the editor's opinions" , "Article that states a newspaper's opinion" , "Chief newspaper article" , "Leading article" .)
