Somehow get it on with Liberal MP in Crucible (7,3)
I believe the answer is:
melting pot
'crucible' is the definition.
(I know that crucible can be written as melting pot)
'somehow get it on with liberal mp in' is the wordplay.
I cannot really see how this works, but
'it' could be 't' (abbreviation. e.g. in 'tis) and 't' is located in the answer.
'liberal' could be 'l' (abbreviation) and 'l' is present in the answer.
'in' is present in the answer.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for melting pot that I've seen before include "Vessel - place for mixture" , "Place where different peoples mingle" , "Place where different peoples mix" , "multicultural area" , "Crucible'" .)
