The European Union is dead as Marley's ghost. Its main hope is that the architecture of the British deal can form a framework for all the members to adopt for themselves 
as a way for all of them to move ahead. A political Union will not happen. They need to find a new way of associating without the massive fiddling of their Parliament into local issues and without a common currency that destroy each counter capacity to manage its monetary policy. The Poms....with Haggis input...can do this...I hope.
