Greek lawmakers leave the hall after the second of three rounds of a presidential vote at the Greek parliament in Athens December 23, 2014. Greek Prime Minister Antonis Samaras failed to capture the support needed to elect a new president in a second round of voting on Tuesday and now needs another 12 votes in the final round next week to avert a snap general election. Samaras' nominee, Stavros Dimas, the only candidate in the race, had not been expected to win the second round and the score of 168 votes was broadly in line with expectations.
