Newspaper editor is brought in as arranged (9)
I believe the answer is:
organised
'arranged' is the definition.
(organising is a kind of arranging)
'newspaper editor is brought in' is the wordplay.
'newspaper' becomes 'organ' (organ can refer to a newspaper or journal).
'editor' becomes 'ed' (abbreviation).
'brought in' means one lot of letters goes inside another.
'organ'+'ed'='organed'
'organed' enclosing 'is' is 'ORGANISED'.
'as' is the link.
(Other definitions for organised that I've seen before include "Put in order" , "Arranged - structured" , "Set up,mobilised" , "Efficient" , "fixed up" .)
