No doubt these dramatic events will be uncomfortable for Britain, but this will all be swept away by bigger events before long. The Europols have not begun to work out a viable solution to their deformed and unworkable currency union, and perhaps no such solution exists. The system will lurch from crisis to crisis until it blows up in acrimony.
By then, a separate cluster will have emerged (not the 10 "outs" against the 17 "ins", always a ludicrous concept), but rather a loose Anglo-Nordic-Swiss grouping that may not do so badly on the fringes and may begin to solidify into a seductively comfortable outer tier.
