Minister taking part in coup as Tory (6)
I believe the answer is:
pastor
'minister' is the definition.
('pastor' can be a synonym of 'minister')
'part in coup as tory' is the wordplay.
'part in' says the answer is hidden in the clue.
'PASTOR' is hidden within 'coup as tory'.
'taking' acts as a link.
(Other definitions for pastor that I've seen before include "Christian minister" , "One with a flock (of people)" , "who may provide a service" , "To spar with clergyman" , "Minister; shepherd" .)
