German leaders right and left unleashed a barrage of criticism at Greece Prime Minister Alexis Tsipras on Sunday for rejecting an offer that could have unlocked rescue funds to resolve the debt crisis. Chancellor Angela Merkel's allies and the leaders of her centre-left coalition partners condemned Greece's leftist government, reflecting pent-up public frustration. Germany is the biggest European contributor to the bailout programmes that have kept Greece afloat for the past five years. Opinion polls now show a majority of Germans want Greece to leave the euro zone.
