That Spectator article is excellent - it addresses the point of sovereignty in a calm and well thought out way using only facts to back up the writers position rather than speculation or plain inaccuracies - 10/10 - if only there were more like this coming from both sides.

It crystallises the choice on this subject - the UK as an independent state or ultimately a member state of a Federal States of Europe - therein lies the real choice.  

It is a shame that not one single politician from either side is willing to address the benefits that would come from being part of such a federation - leavers reference the point as though an FSE would be the end of the world as we know it and stayers just deny it could ever happen.
