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'm not sure about 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 give a lot more credence to this answer).
'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' is the 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" .)
