It's been inching closer - remember even a downward trend can throw a brief spike.
FPTP simply isn't going to "work" with more parties. Since no one has addressed whether "democracy" and "representation" are equivalent I guess the answer must be that as long as we have a "government" (i.e. a party with a majority in Westminster) then representation is irrelevant. As indeed it has been for so long in Englands history,
Imagine a result that returned a parliamentary majority on 40% of votes cast. Which suggests that about 70% of the population did not vote for the ruling government
Imagine a workplace where 30% of the employees organised everything for the other 70%.
Meals ? Vegans can fuck off.
Toilets ? Well that 30% is probably 80% male. So no need for female toilets.
And so on.
Obviously the permathickies of this world like Badenoch and Jenrick would think such a situation is a Good Thing. However the more sanguine minds have already started casting the runes for such scenarios because if you want to know what a civil war looks like, you may just find out.
Even I would struggle to feel bound to a government based on 30% of the population.
