Anonymous newspaper article uncovered abuse by CO (8)
I believe the answer is:
columbus
'anonymous newspaper' is the definition.
Although both the answer and definition are singular nouns, I don't understand how one could define the other.
'article uncovered abuse by co' is the wordplay.
'article' becomes 'lum' (I can't justify this - if you can you should believe this answer much more).
'uncovered' says to take the centre.
'by' says to put letters next to each other.
The middle of 'abuse' is 'bus'.
'lum'+'bus'='lumbus'
'lumbus' put after 'co' is 'COLUMBUS'.
(Other definitions for columbus that I've seen before include "State capital of Ohio" , "film director" , "1492 voyager" , "Discoverer of the New World" , "CARRY ON FILM" .)
