Thank you for the link. It is interesting and it deserves further thought when I have more time. My eye was, though, drawn to this quote:
“the concept of ever closer union allows for different paths of integration for different countries, allowing those that want to deepen integration to move ahead, while respecting the wish of those who do not want to deepen any further”.
Ever-closer union for countries is therefore a live concept. The euro may only survive if there is further integration among its members. As the eurozone becomes more integrated, what is the future for a major country in the EU but outside the more integrated eurozone?
Those committed to the EU project like Michael Heseltine ultimately see the UK as part of a more integrated Eurozone. I see the logic of that position but it is not one I have opted for.
I might ask what was the need for the Cameron opt-out if there is no ever-closer union?
I do appreciate the link and I will ponder further but now, Sainsbury's beckons and maybe some exercise en route to a couple of Spring half marathons.
