Can't do without Tyneside newsmen? (5)
I believe the answer is:
needs
'can't do without' is the definition.
(I've seen this before)
'tyneside newsmen?' is the wordplay.
'tyneside' becomes 'ne' (region in North East of England).
'newsmen?' becomes 'eds' (I can't justify this - if you can you should believe this answer much more).
'ne'+'eds'='NEEDS'
Can you help me to learn more?
(Other definitions for needs that I've seen before include "necessity once" , "What is required" , "Necessities" , "shopping-list, say" , "Essentials" .)
