Ahead of the summit's start, German Chancellor Angela Merkel and French President Nicolas Sarkozy, the eurozone's key players, agreed on a "common position" after late-night talks in Berlin.

The French government said the agreement was a precondition to ending the eurozone debt crisis.

"It was an indispensable precondition to reassure our partners," government spokeswoman Valerie Pecresse told France 2 television.

"We must build the widest possible consensus and the first building block of that consensus, is obviously a common position" between France and Germany, she added.
