Leader? Real idiot, unfortunately (9)
I believe the answer is:
editorial
'leader?' is the definition.
(I've seen this before)
'real idiot unfortunately' is the wordplay.
'unfortunately' is an anagram indicator.
'real'+'idiot'='realidiot'
'realidiot' anagrammed gives 'EDITORIAL'.
(Other definitions for editorial that I've seen before include "Statement of a newspaper's opinion" , "Article giving a newspaper's opinion" , "Newspaper opinion piece" , "leader, perhaps" , "Newspaper item" .)
