Oh yeah, I lived in the UK for over a decade, right after having lived in The Netherlands (who have Proportional Vote) for almost a decade, and am well aware of just how horribly rigged the British voting and political system are, especially after Brexit (which I saw first hand, after which I did my own personal Leave of a country I, frankly, see no positive future for)

My own country, Portugal, has it's own rigged system that gives nice 15% boosts to representativeness versus actual votes received, for the 2 major parties, though fortunatly it's not just one seat per electoral circle, so whilst nowhere as Democratic as PV at least there are 8 parties with parliamentary representation, small parties still get half the parliamentarians that their votes would've yielded under PV (unlike in the UK where the Green Party gets 1 million votes in 40 million - so 2.5% of votes - and ends up with 1 seat in 600 - so about 0.15% of seats), and even with the rigging the upcoming elections (next month) do not seem on track to yield a parliamentary majority for any one party.
