Tory trick (3)

I believe the answer is:

con

I believe this is a double definition.

'tory' is the first definition.
(abbreviation for Conservative)

'trick' is the second definition.
(I've seen this before)

(Other definitions for con that I've seen before include "Trick, deceive" , "do something?" , "Deceive; disadvantage" , "Swindle, deception" , "Informally swindle" .)

I've seen this clue in The Times.
