British conservative (4)
I believe the answer is:
'british conservative' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for tory that I've seen before include "A British Conservative" , "type on right? Yes" , "Traditionalist" , "Opponent of 8 Down and 14 Across, partner of 14 Down?" , "English Conservative politician or Donegal island" .)
