Lest anyone else be labouring under such a delusion, the UK is not leaving the EU any time soon and the UK PM Teresa May (unelected) has pretty well said as much. In any case, under article 50 it would take about 3 years, but since article 50 is treason and should never have been signed in the first place, then there is another quagmire to negotiate. It is the 1972 Agreement that is of significance here wrt a UK withdrawal from the EU and afaiaa that has never even been mentioned in the UK MSM- I doubt it ever will be.
If the UK status within the EU, or anywhere else, could be influenced by a vote then rest assured voting would be abolished.
The EU has its roots in the Pan European Movement going back to the 1920s: Coudenhove Kalergi, Warburg money, the Hapsburgs … check out the Charlemagne Prize. The European project is right on track, make no mistake.
Sovereignty??? pah!
