Remove from office some unscrupulous Tories (4)
I believe the answer is:
oust
'remove from office' is the definition.
(I've seen this before)
'some unscrupulous tories' is the wordplay.
'some' indicates the answer is hidden within the clue (some parts of the word are used).
'OUST' is hidden in the letters of 'unscrupulous tories'.
(Other definitions for oust that I've seen before include "Remove from a position of power" , "Put out, say of office" , "Show the door to" , "Drive out, expel" , "Turf out" .)
