There's no federal government in the UK, nor constitution

You are technically correct. But the distinction between devolution and a Federation of states gets very blurry when you take a look at what's happening with voting in the US these days.

You are technically incorrect about the UK not having a constitution. It's just not all compiled into a single written document.

There is absolutely a Constitution in the UK, it is simply not codified into a single document.

More importantly, the UK is a Constitutional Monarchy, with ultimate legislative power vested in Parliament rather than the Monarch.

		I find it weird that people would downvote this, I know you should not complain about it, but this comment is correct. The UK does have a (uncodified) constitution. Also of note; even countries with a codified constitution have parts that are uncodified.
