Shares in possession of ministerial responsibility (9)
I believe the answer is:
portfolio
This clue might be a double definition.
'shares' is the first definition.
(I've seen this before)
'possession of ministerial responsibility' is the second definition.
'portfolio' can be an answer for 'responsibility' (I have seen 'governmental responsibility' mean 'portfolio' so perhaps 'responsibility' could also mean 'portfolio'). I am unsure of the 'possession of ministerial' bit.
'in' acts as a link.
Can you help me to learn more?
(Other definitions for portfolio that I've seen before include "Collection of papers" , "art collection" , "mixed dish" , "artist's sample work" , "Case for loose paper, drawings etc" .)
