Knock back complaint about current collection of politicians (10)
I believe the answer is:
parliament
'knock back' is the definition.
The definition and answer can be both acts as well as being singular nouns.
Perhaps you can see a link between them that I can't see?
'complaint about current collection of politicians' is the wordplay.
I cannot quite understand how this works, but
'about' could be 'a' (abbreviation in Chambers) and 'a' is found within the answer.
'current' could be 'i' (physics symbol) and 'i' is present in the answer.
'complaint' could be 'lament' (lament is a kind of complaint) and 'lament' is found within the remaining letters.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for parliament that I've seen before include "UK legislature" , "Diet" , "Houses" , "Legislative body" , "Legislative assembly" .)
