In the foreground we still see David Cameron trudging forlornly round the capitals of Europe seeking support for his wish to negotiate a “new relationship” for Britain in a “reformed EU” – before he can allegedly arrive next month at some kind of “a deal”. We still hear it claimed that he could stage his referendum as early as this summer. Meanwhile, ever more groups emerge to jockey for the lead role in the “leave” campaign, none of which, it seems, has any practical plan as to how we might actually extricate ourselves from the EU in a sensible way – let alone any positive vision of how Britain could flourish outside it.
