Irish boy held by mum or dad in legislative assembly (10)
I believe the answer is:
parliament
'legislative assembly' is the definition.
(I know that parliament is a type of legislative assembly)
'irish boy held by mum or dad' is the wordplay.
'irish boy' becomes 'liam' (I've seen this before. I am not sure about the 'irish' bit.).
'held by' means one lot of letters goes inside another.
'mum or dad' becomes 'parent' (I've seen this before).
'liam' inserted inside 'parent' is 'PARLIAMENT'.
'in' is the link.
Can you help me to learn more?
(Other definitions for parliament that I've seen before include "Diet" , "The law is laid down here" , "UK legislature" , "Legislative assembly" , "Legislative body" .)
