Lead journalist travelled northbound carrying computers, etc. (6)
I believe the answer is:
editor
'lead journalist' is the definition.
'editor' can be an answer for 'journalist' (senior journalist). I'm not sure about the 'lead' bit.
'travelled northbound carrying computers etc' is the wordplay.
'travelled' becomes 'rode' (eg travelled on a horse).
'northbound' says the letters should be written backwards.
'carrying' means one lot of letters goes inside another.
'computers etc' becomes 'it' (short for Information Technology).
'rode' back-to-front is 'edor'.
'edor' enclosing 'it' is 'EDITOR'.
Can you help me to learn more?
(Other definitions for editor that I've seen before include "Newspaper or publication chief" , "One is in charge of publication" , "Senior publisher" , "Head of a newspaper say" , "Person in charge of newspaper" .)
