Stamouli and Walker of WSJ describe the last days of negotiations in June before Greece pulled out its negotiating team, and German chancellor Merkel decided to call off the bailout of Greece. The impasse was over pension cuts and vaue added taxes, yet the negotiations were still going over details when Tsipras pulled out Greece's negotiating team with the surprise announcement of a referendum on July 5, 2015. By saying the Syriza party would call for a "no" vote Tsipras alienated public opinion in Germany. Chancellor Merkel seeing the shift in domestic opinion favoring Greece's exit from the euro during the tense months of negotiations with the Syriza government and acrimonious charges, moved to call off a continued EU bailout of Greece.
