Unlike all other squeaky clean politicians are you saying?- What ever either of us may think of UKIP or any of their Reps they are the only political party based in the grass roots of England and Wales as once Labour was - you live in a bubble which does not much like the main body of England and Wales and wishes the hoi polloi to bend to your ways of thinking - not that I have ever come across a remoaner to have done much thinking -
Sovereignty is the people, in our instance Parliament is given by the people that, our, Sovereignty in office - Parliament handed back our Sovereignty to us for the referendum - basta, it is done, OUT the people said - 'as we were', repeal the 1972 Act. No protectionist single market, no supreme powers over our laws and institutions, over our trade and all other relationships including our culture and history.
Why did they hand it back to us, that which is ours in the first place? Because they had no legal right ( Bill of Rights) to give away any of our Sovereignty in the first place - it was not their to give - it is ours.
It was a treasonous act - which is why the Blairs and etc who signed any EU treaty are sh'itting themselves now -
As a ps I have not looked into the EU allegations against UKIP so can't comment on this particular case -
