After power? This ends the work of Parliament (4)
I believe the answer is:
acts
'work of parliament' is the definition.
'acts' can be an answer for 'work' (I have seen 'spiritual work' mean 'acts' so perhaps 'work' could also mean 'acts'). I'm unsure of the 'of parliament' bit.
'after power? this ends' is the wordplay.
'after' means one lot of letters go next to another.
'power?' becomes 'ac' (AC is an example).
'ends' means to remove the middle letters.
'this' with its middle taken out is 'ts'.
'ac' next to 'ts' is 'ACTS'.
'the' acts as a link.
Can you help me to learn more?
(Other definitions for acts that I've seen before include "Deeds; NT book" , "straight after John" , "Decrees" , "Performances" , "functions" .)
