Greece goes to polls today in a snap general election that is likely to see the ruling Conservatives lose their grip on power. Opinion polls put the opposition Socialists led by George Papandreou ahead of Prime Minister Costas Karamanlis' New Democracy party. Mr. Karamanlis was only half way into his four-year term when he called the election in early September. He said he wanted a new mandate to tackle Greece's economic problems. However, the government has been hit by a series of corruption scandals. Mr. Karamanlis' opponents say he has failed to fulfill promises to clean up public office and to modernize the country. Mr. Papandreou, of the Panhellenic Socialist Movement (Pasok), is promising to build a green economy and bring in foreign experts to help Greece overcome its problems.
