Mussolini’s system for division to leave Hungary after France advanced (7)
I believe the answer is:
fascism
'mussolini's system' is the definition.
'fascism' can be an answer for 'system' (I have seen 'Authoritarian system ' mean 'fascism' so perhaps 'system' could also mean 'fascism'). I am unsure of the 'mussolini's' bit.
I don't understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for fascism that I've seen before include "Political theory advocating authoritarian government" , "Form of right-wing authoritarian nationalism" , "System of extreme right-wing dictatorial government, like Mussolini's" , "Authoritarian style of government" , "Mussolini movement" .)
