Disgraced bogus journalist (6)
I believe the answer is:
shamed
'disgraced' is the definition.
('shame' can be a synonym of 'disgrace')
'bogus journalist' is the wordplay.
'bogus' becomes 'sham' (both can mean fake).
'journalist' becomes 'ed' (short for editor).
'sham'+'ed'='SHAMED'
(Other definitions for shamed that I've seen before include "Disgraced or humiliated" , "brought into disrepute" , "Made to feel humilated" , "Made to feel guilty and inferior" , "He's mad (anag)" .)
