Multiple federations in fact:
Britain, being the federation of England and Wales.
Great Britain, being the federation of England, Wales and Scotland.
The United Kingdom, being the federation of England, Wales, Scotland and Northern Ireland.
So the EU is merely another layer, but even if we leave the EU, there is still a superior body having power over us.
Namely the United Nations which as a body has far more power over us than most realise. Just have a look at the transport regulations on
this UNECE web page which affect our electric two wheelers too.
And the sub-heading "How we impact your daily life" on
this web page
So much for "Taking back Control", in this globalised world that isn't possible.
*UNECE = United Nations Economic Commission for Europe
You see, another Commission in charge of many aspects of your life.
