Continue working with journalists old and new (5,2)
I believe the answer is:
press on
'continue working' is the definition.
'press on' can be an answer for 'continue' (to press on with something is to continue with it). I'm not sure about the 'working' bit.
'journalists old and new' is the wordplay.
'journalists' becomes 'press' (the press can mean the newspaper industry).
'old' becomes 'o' (abbreviation).
'and' says to put letters next to each other.
'new' becomes 'n' (common abbreviation eg NT for New Testament).
'press'+'o'+'n'='PRESS ON'
'with' acts as a link.
Can you help me to learn more?
(Other definitions for press on that I've seen before include "Continue going forward" , "Continue (with action)" , "Persevere doggedly, quickly" , "don't stop!" , "Keep going forward" .)
