United Kingdom

Also, in my view the EU is quite undemocratic. The separate Council, Commission and Parliament are an affront. Especially the fact that the Parliament, which represents the electorate, does not have the power to introduce legislation.

You do realise that the entire structure of the EU was primarily dreamt up by British legal experts? It's quite literally one of the best, most robust and most competent systems of governance in the world.

Yes, Parliament can't introduce legislation by themselves, but that's because we don't want populists like Farage, Boris or Trump to do that. They're charismatic, but not actually competent. That's why talented legal experts in the European Commission (who are each appointed by elected governments of member states, the UK had 6 iirc), people who actually know how law works, write the laws. The elected MEP's vote on the laws.

However even here we're missing the fact that the European Parliament (EP) do have a say in the legislation. The EC writes an "Impact Assessment" with rough draft of the law they're thinking of writing (which anyone can comment on), then this is presented before Parliament who propose and discuss amendments. So it's completely disingenuous to imply that the elected EP is somehow beholden to the "unelected" (but chosen for competency by elected member governments) EC bureaucrats.

And all that skips around what starts the EC's initial proposal. Aside from occassionally writing laws off their own backs, the EC responds to requests from:

• The European Council (heads of state or government of each EU country)
• The Council of the European Union (government ministers from each EU country)
• The European Parliament (directly elected by EU citizens)
• Citizens themselves, following a successful European Citizens’ Initiative

That's right, not only can Parliament demand new legislation (they just have to get the big boy lawyers to write it for them), but individual citizens can directly!

Parliament has the final say in whether or not legislation is implemented. That's completely democratic. What you call "an affront" is actually competent people writing effective legislation. Rather than bullshit like the Rwanda deal which states the UK will accept vulnerable refugees from Rwanda in exchange for the small boat migrants to Rwanda (all paid for by the UK taxpayer), or the general ineptitude of no legislation at all and a Hard Brexit causing issues like sewage being dumped in our rivers since water companies now face restrictions on importing treatment chemicals from the EU.
