It’s a stupid system anyway. Many are pushing for it to change. It could happen .
Are you looking forward to a proportional voting system without electors in the US as well??
There are no absolute “fair” systems. The first past the post system almost always guarantees a majority government. Yes, the Reform party received more than 4 million votes and only 4 seats in the Commons, whereas the Lib Dems garnered roughly 3.5 million votes and received (so far) 71 places in the Parliament.
So, is a proportional system fairer then? Not necessarily. We have lots of examples here in post-war Europe where very small, often extreme parties have made up the balance of power. In Sweden we have had several periods when the former Communists (the Left Party) or the Greens (both in the range of 4 - 8%) have been able to run roughshod over the majority of the voters because they were able to make up the difference between one side of the political spectrum (usually the socialists) and 50.1%.
So, unless you want to be ruled by the socialists on the coasts I suggest you stick with the system you have.
