A new party led by economists, jurists, and Christian Democrat rebels will kick off this week, calling for the break-up of monetary union before it can do any more damage.

"An end to this euro," is the first line on the webpage of Alternative für Deutschland (AfD). "The introduction of the euro has proved to be a fatal mistake, that threatens the welfare of us all. The old parties are used up. They stubbornly refuse to admit their mistakes."

They propose German withdrawl from EMU and return to the D-Mark, or a breakaway currency with the Dutch, Austrians, Finns, and like-minded nations. The French are not among them. The borders run along the ancient line of cleavage dividing Latins from Germanic tribes.

The plans draw on work by Hans-Olaf Henkel, former head of Germany's industry federation (BDI) and a chastened europhile -- the "worst error of my professional life", he told me.

The appeal of German exit is obvious. It is the least traumatic way to end the 20pc to 30pc misalignment between North and South, the cancer eating Europe. Club Med keeps the euro. It enjoys instant devaluation, while still able to uphold euro debt contracts. The spectre of sovereign defaults recedes.
