Journalist travelled up to cover it (6)
I believe the answer is:
'journalist' is the definition.
'travelled up to cover it' is the wordplay.
'travelled' becomes 'rode' (I've seen this before).
'up' is a reversal indicator (in down clue: letters go upwards).
'to cover' is an insertion indicator.
'rode' back-to-front is 'edor'.
'edor' going around 'it' is 'EDITOR'.
(Other definitions for editor that I've seen before include "Person who revises and prepares for publication" , "Person who determines the final content of a text" , "Chief journalist" , "Director of publication" , "Wapping boss" .)
