Like unedited report and leader in Guardian, agreeing (9)
I believe the answer is:
assenting
'agreeing' is the definition.
(synonyms)
'like unedited report and leader in guardian' is the wordplay.
'like' becomes 'as'.
'unedited report' becomes 'sentin' (I can't explain this - if you can you should give a lot more credence to this answer).
'and' is a charade indicator (letters next to each other).
'leader in' indicates taking the first letters.
The first letter of 'guardian' is 'g'.
'as'+'sentin'+'g'='ASSENTING'
Can you help me to learn more?
(Other definitions for assenting that I've seen before include "Saying yes" , "Agreeing" .)
