Humiliated by a bogus journalist (7)
I believe the answer is:
ashamed
'humiliated' is the definition.
(I've seen this before)
'by a bogus journalist' is the wordplay.
'by' means one lot of letters go next to another.
'bogus' becomes 'sham' (I've seen this in other clues).
'journalist' becomes 'ed' (short for editor).
'a' put next to 'sham' is 'asham'.
'asham'+'ed'='ASHAMED'
(Other definitions for ashamed that I've seen before include "Feeling bad, having done something wrong" , "Humiliated" , "hanging his head" , "Feeling remorse and guilt" , "He's Adam (anag.)" .)
