Expert commentator (6)
I believe the answer is:
pundit
'expert commentator' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for pundit that I've seen before include "Learned Hindu or general expert" , "An expert or critic in a particular field" , "Expert (sometimes self-appointed)" , "Learned authority" , "A learned Hindu or expert generally" .)
