BERLIN, GERMANY - DECEMBER 15: In this photo illustration plastic, toy construction workers stand around a one Euro coin on December 15, 2010 in Berlin, Germany. European leaders are scheduled to meet at a European Union summit in Brussels tomorrow to discuss measures on how to stabilize the Euro that could include the creation of a permanent eurozone bailout system. The Euro has come under severe strain in the last year through the economic problems of some of its members, and a group of nations nicknamed the PIIGS (Portugal, Ireland, Italy, Greece and Spain) have been named by many analysts as the countries posing the biggest threat to the common currency's stability.
