European following new editor's demands (5)
I believe the answer is:
needs
'demands' is the definition.
(I know this)
'european following new editor's' is the wordplay.
'european' becomes 'E' (abbreviation e.g. EU).
'following' says to put letters next to each other.
'new' becomes 'n' (common abbreviation eg NT for New Testament).
'editor's' becomes 'ed's'.
'e' after 'n' is 'ne'.
'ne'+'eds'='NEEDS'
(Other definitions for needs that I've seen before include "Is desperate for" , "Necessitates" , "Requires, is in want of" , "Calls for" , "'..... must when the devil drives'" .)
