Chief journalist (6)
I believe the answer is:
editor
'chief journalist' is the definition.
(I've seen this before)
This is all the clue.
(Other definitions for editor that I've seen before include "Top journalist" , "Person who determines the final content of a text" , "Person who revises and prepares for publication" , "Do tie out the newspaper head" , "One prepares a work for publication" .)
