ATHENS, GREECE - JANUARY 25: Supporters of Alexis Tsipras, leader of Syriza left-wing party, cheer during a rally outside Athens University Headquarters January 25, 2015 in Athens, Greece. According to the latest opinion polls, the left-wing Syriza party are poised to defeat Prime Minister Antonis Samaras' conservative New Democracy party in the election, which has taken place today. European leaders fear that Greece could abandon the Euro, write off some of its national debt and put an end to the country's austerity by renegotiating the terms of its bailout if the radical Syriza party comes to power. Greece's potential withdrawal from the eurozone has become known as the 'Grexit'. (Photo by Milos Bicanski/Getty Images)
