Right to escape the Westminster madhouse? (9,6)
I believe the answer is:
political asylum
'right to escape the westminster' is the definition.
I know nothing about this answer so I can't judge whether it can be defined by this definition.
'madhouse?' is the wordplay.
I cannot quite understand how this works, but
'madhouse?' could be 'asylum' (madhouse is a kind of asylum) and 'asylum' is found within the answer.
The remaining letters 'political' 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 political asylum that I've seen before include "State protection" , "refuge?" .)
