Rent such as minister retains (5)
I believe the answer is:
chasm
'rent' is the definition.
(I've seen this before)
'such as minister retains' is the wordplay.
'retains' says the answer is hidden in the clue.
'CHASM' is hidden in the letters of 'such as minister'.
(Other definitions for chasm that I've seen before include "big break?" , "Deep opening in the ground" , "Great divide" , "One yawns" , "What's split" .)
