Such was the "tough, even violent" atmosphere, in the words of one participant, that after an overnight break the German and French finance chiefs, Wolfgang Schaeuble and Michel Sapin, sat down to clear the air between them before resuming on Sunday. Schaeuble also crossed swords with ECB governor Mario Draghi, snapping at the Italian central banker "I'm not stupid!" "It was crazy, a kindergarten," said a source describing the overall course of nine hours of talks on Saturday among weary ministers attending their sixth emergency Eurogroup in three weeks. "Bad emotions have completely taken over." Schaeuble and others seemed to favour a "Grexit", another participant said.
