Greece’s Tsipras: We Want Euro, but Not Austerity

By Michelle Caruso-Cabrera and Jennifer Leigh Parker

Tsipras (pronounced SEE-Pras), who was unable to form a coalition government this week after his party came second in Sunday’s election, said a Greek exit from the euro zone would be “disastrous.”

Tsipras said he is willing to negotiate with the so-called troika — the International Monetary Fund , the European Union, and theEuropean Central Bank — to keep Greece in the euro zone.
