A Look at the Main Greek Party Leaders Opinion polls indicate seven parties will likely enter Greece's Parliament after Sunday's election. Here are the main candidates: The U.S.-educated economist, whose party won an inconclusive victory on May 6, presents Sunday's vote as a stark choice between staying in the euro and reverting to the country's old drachma currency, which he claims will happen if his main left-wing opponents win. Opinion polls show Samaras' conservative party neck and neck with the Syriza radical left coalition. New Democracy won just under 19 percent last month, but without enough seats in Parliament to govern alone, and was unable to throw together a coalition. Samaras, 61, broadly upholds Greece's bailout commitments but wants them diluted through a two-year extension, until 2016. He has pledged to cut tax rates and boost the income of low-earning pensioners, large families, farmers, police and fighter pilots. He wants to "retake" Greek cities from illegal migrants and scrap laws granting citizenship to second-generation immigrants. A rapid-rising conservative star in the late 1980s, Samaras briefly served as finance minister and as foreign minister when Greece's name dispute with Macedonia broke out in 1991. Following a decade in the political wilderness, Samaras was readmitted to New Democracy and became its leader after its dismal showing in the 2009 election. At 37, the civil engineer and former student activist is Greece's youngest party head. Riding a wave of anger at the country's harsh austerity program, Tsipras led Syriza to an unprecedented second place in last month's polls with 16.8 percent of the vote. A mainstay of the anti-austerity movement, Tsipras has alarmed many in Greece and abroad by saying he wants to scrap Greece's bailout deals, nationalize banks, restore drastically reduced pensions and salaries, and cancel plans to sack 150,000 civil servants. Nevertheless, he backs Greece's cherished position in the European Union and the eurozone, and maintains that the country can stay within both groups even if it reneges on its austerity commitments. Syriza is a grouping of politicians from 12 disparate entities, and some have suggested that they would not be averse to Greece adopting the drachma. Under Tsipras, the party alienated many Greeks by backing protesters during extensive riots in 2008 that followed the fatal police shooting of an Athens teenager. The 55-year-old professor of constitutional law served for nine months as the debt-crippled nation's finance minister, successfully negotiating a second international bailout and the biggest debt relief deal in history. PASOK paid heavily for the crippling austerity program that allowed Greece's two bailouts but was not accompanied by convincing structural reforms. The party that won a landslide victory in 2009 received a meager 13.2 percent of the vote on May 6. As Socialist leader, Venizelos has pledged to shield Greeks from new across-the-board income cuts, while respecting the country's bailout commitments. He is seeking a three-year deadline extension in Greece's austerity program, and has promised to overhaul the country's inefficient tax system.
