Th government can say what it likes. You don't believe everything that politicians say do you?
Legally and constitutionally the referendum was advisory. It has no standing in law. I say you are a smelly poo head - does that make it true?
The U.K. parliament is sovereign. However, as we enter an increasingly globalised world some aspects of sovereignty are shared. If we leave the EU and trade under WTO rules - we will be trading under those rules with no say in how they are made.
In the EU some laws are made (democratically) and we have to abide by them. The key difference is we get a say in how they are made.
Sovereignty is pooled via NATO and the ECHR.
Sovereignty is going to be 100% which ever decision we make. However, in terms of the U.K. no body can bind parliament not even parliament.
You say in reference to my comment on representative democracy You seem to revel in the fact that other people make decisions for you. Have you heard of the concept of self-reliance?
I am not commenting on whether this is right or wrong I am merely explaining to you how the system you value works. I have some significant issues with U.K. democracy but they are based on an understanding of it.
You want to retain the U.K. system of democracy but consistently demonstrate a profound lack of understanding of how it works.
