Journalist travelled back to cover it (6)
I believe the answer is:
editor
'journalist' is the definition.
(thesaurus)
'travelled back to cover it' is the wordplay.
'travelled' becomes 'rode' (I've seen this in other clues).
'back' says the letters should be written in reverse.
'to cover' is an insertion indicator.
'rode' written backwards gives 'edor'.
'edor' placed around 'it' is 'EDITOR'.
(Other definitions for editor that I've seen before include "Source of leaders" , "Top journalist" , "Newspaper executive" , "Times boss maybe" , "One expected to make final" .)
