The investor and hedge fund manager George Soros not only built a billion dollar fortune, but also a legendary reputation when he successfully speculated against the overvalued British pound in the 1990s.

His latest alliance is all the more astonishing: together with Reiner Hoffmann, the chairman of the German Trade Union Confederation (DGB), the ex-speculator has written an appeal to the member states of the EU.

In it, they and around 150 scientists, representatives of NGOs and union leaders call for a revolution at EU level: a permanent EU budget.
