Leader adroit with lie unfortunately (9)
I believe the answer is:
editorial
'leader' is the definition.
(type of newspaper article)
'adroit with lie unfortunately' is the wordplay.
'with' is a charade indicator (letters next to each other).
'unfortunately' is an anagram indicator (a bad or unfortunate spelling).
'adroit'+'lie'='adroitlie'
'adroitlie' with letters rearranged gives 'EDITORIAL'.
(Other definitions for editorial that I've seen before include "matter of opinion" , "Article written" , "Article expressing the views of the publication" , "(Paper's) leader" , "Leading article" .)
