Why is this such a big deal. You vote for the person you want to represent you and your area. They within their party then vote for a person to lead them. Nobody has voted for any PM in history, this is not how our current system works.
I willl never vote for the Tories, as they are untrustworthy, and will always look after those with the money, not those who really need the help. Labour have not done well, and in places done terribly. But the rights and lifes of those who don’t earn £30k or over are probably in a better place, than they ever were before.
