Winding up Conservative being defeated (7)
I believe the answer is:
closing
'winding' is the definition.
The answer and definition can be both acts as well as being singular nouns.
Maybe you can see an association between them that I can't see?
'up conservative being defeated' is the wordplay.
I cannot really understand how this works, but
'conservative' could be 'c' (UK political abbreviation) and 'c' is found within the answer.
The remaining letters 'losing' is a valid word which might be clued in a way I don't understand.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for closing that I've seen before include "Ending" , "Shutting" , "packing up" , "Finishing" .)
