Editorial comment describing provocative questions - clear it needs editing (7,7)
I believe the answer is:
leading article
'editorial comment' is the definition.
'leading article' can be an answer for 'comment' (thesaurus). I am not certain of the 'editorial' bit.
'provocative questions clear it needs editing' is the wordplay.
'provocative questions' becomes 'leading' (I can't explain this - if you can you should believe this answer much more).
'needs editing' is an anagram indicator (I've seen 'needing editing' mean this).
'clear'+'it'='clearit'
'clearit' anagrammed gives 'article'.
'leading'+'article'='LEADING ARTICLE'
'describing' acts as a link.
Can you help me to learn more?
(Other definitions for leading article that I've seen before include "Newspaper's comment" , "such as The Times has" , "Editorial" .)
