ATHENS, GREECE , DECEMBER 17: Alexis Tsipras, leader of the main opposition left-wing Syriza, waits during the first round of voting to elect a new Greek president at the Parliament on December 17, 2014 in Athens, Greece. The Greek parliament has failed to elect a new president after the first of three rounds of voting. The government's candidate, Stavros Dimas got 160 votes - 40 short of an outright win. If he fails to get elected after the next two rounds there will be a general election. (Photo by Milos Bicanski/Getty Images)
