What system did Italy have in the past didn't they have many elections due to coalitions collapsing.
Also I think someone mentioned the number of MPs in the UK isn't this being looked at.the recommendations was to reduce the number.
Labour refused to support it, because in the past they have benefited from the current situation - it appears that may have changed with this election, so maybe, just maybe, it might happen. That said, BrExit rather than domestic politics is going to be the priority, so this still may not happen.
