Pudding must include minor responsibility later (10)
I believe the answer is:
afterwards
'later' is the definition.
('afterwards' can be a synonym of 'later')
'pudding must include minor' is the wordplay.
'pudding' becomes 'afters' (I've seen this before).
'must include' means one lot of letters goes inside another.
'minor' becomes 'ward' (I've seen this in other clues).
'afters' going around 'ward' is 'AFTERWARDS'.
'responsibility' acts as a link.
I am not very happy about this link. It may belong to another bit of the clue.
Can you help me to learn more?
(Other definitions for afterwards that I've seen before include "Subsequently" , "Later on" .)
