Tory knight, possibly a fraudster (3,3)
I believe the answer is:
con man
'a fraudster' is the definition.
I can't judge whether this definition defines the answer.
'tory knight possibly' is the wordplay.
'tory' becomes 'con' (abbreviation for conservative).
'knight possibly' becomes 'man' (knight is a kind of man).
'con'+'man'='CON-MAN'
Can you help me to learn more?
(Other definitions for con man that I've seen before include "A professional swindler" , "State of NE Africa" , "One who does" , "A male confidence swindler" , "A modern swindler who fools people" .)
