But it isn't the Government who gets to vote for it. It's conservative party members.
There are around 200k people (millionaires/ultra right-wing/kids who were bullied in school/blatant racists), who reflect an extreme end of the political scale, deciding on the leadership of our country for the second time in less than 2 months. These clowns voted for Truss in the first place so the truth is either:
1 - We are letting 200k inept morons (who thought Truss would make a good PM) decide on our collective future, again!
2 - Truss genuinely was the best candidate for the job, in which case whoever follows is going to be even worse!
Either way, we're completely fucked in an incredibly undemocratic fashion.
