The UK doesn’t even have a single sourced constitution. Just random things from random times in random documents. Parliament is essentially king and can just make any law it wants at anytime with a basic majority. Nothing is codified. There are no real standards.

The UK is one of the most arbitrarily defined places in terms of law. It’s why they can have and enforce a 2-tier system. “Stirring things up” is literally a charge a judge can arbitrarily rule on. Place is hilarious.
