Newspaper chief travelled back to cover it (6)
I believe the answer is:
editor
'newspaper chief' is the definition.
(I've seen this before)
'travelled back to cover it' is the wordplay.
'travelled' becomes 'rode' (I've seen this in other clues).
'back' shows that the letters should be reversed in order.
'to cover' is an insertion indicator.
'rode' backwards is 'edor'.
'edor' placed around 'it' is 'EDITOR'.
(Other definitions for editor that I've seen before include "Person in charge of paper" , "Press fellow" , "Or tied up my boss" , "Press boss" , "One responsible for leader" .)
