I think all these protests are going to lead to Starmer cracking down on them, some new legislation will be forced through that means they can disperse and arrest everyone on the grounds of protecting the peace or something.
This will then lead to more targeted attacks on the hotels, police and infrastructure like we see with the bladerunners. This will progressively get worse until there are deaths and then Starmer will crack down further. There will be blanket censorship, full-on purge of anyone supporting nationalism and a massive increase in immigration the likes of which will make the current numbers seem like a drop in the ocean.
