This is the part that doesn't make any sense to me.
Your entire country is made up of current Acts of Parliament. There's nothing else than that. There's no such thing as a constitution.
That's what a constitution is. It's a law of special status above all other law. But you refuse in this country to understand that.
That is not a constitution.
You're now trying to make "constitutional" guarantees to various people, but you've got no constitution to guarantee them with.
The European Union has been serving that function for the last 50 years. That was the superior law which any Act of Parliament must be subordinate.
It's exactly the same. You're just relying on superstition and witchcraft.
