Greek radical-left Syriza party leader Alexis Tsipras (C) arrives at the election campaign headquarters of the Syriza party in Athens on September 20, 2015. With over half of the votes counted, Tsipras' Syriza party won 35.54 percent of the vote against 28.07 percent for conservative New Democracy and is likely to again form a coalition government with the nationalist Independent Greeks (ANEL) party.
