Bathroom fixture for senior ministers (7)
I believe the answer is:
cabinet
'senior ministers' is the definition.
(I've seen this before)
I don't understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for cabinet that I've seen before include "up against the wall?" , "It may be shelved" , "accommodating senior ministers" , "some PMs dislike?" , "Type of cupboard" .)
