EU, IMF Aid Package for Greece Agreed Upon Greek PM Papandreou says package necessary for Greece to avoid bankruptcy, country must be willing to make major sacrifices VOA News 02 May 2010 A protester shouts slogans during a demonstration in the Greek port city of Thessaloniki, 1 May 2010 Photo: AP A protester shouts slogans during a demonstration in the Greek port city of Thessaloniki, 1 May 2010. Thousands of protesters gathered in Thessaloniki and other Greek cities Saturday for May Day rallies fueled by anger at expected harsh austerity measures needed to secure rescue loans. The Greek prime minister says his government has reached an agreement with the European Union and the International Monetary Fund on a multi-billion-dollar financial bailout package. Prime Minister George Papandreou said Sunday the package is necessary for Greece to avoid bankruptcy, and the country must be willing to make major sacrifices. Details of the package, said to be worth $160 billion, are to be announced later Sunday. The head of the European Commission, Jose Manuel Barroso, supports the emergency aid package for Greece. President Barroso said the aid package will be "decisive" in getting Greece's economy back on track, and will keep the crisis from further threatening the financial health of other EU nations. Thousands of protesters rallied in Athens Saturday against the government's plan to make deep budget cuts. Protesters struck police with sticks and threw fire bombs in the Greek capital at the May Day rally. Police fired tear gas to break up the crowds. Greece's public sector union has been leading opposition to austerity measures the government is planning as part of the international economic rescue package. Mr. Papandreou has told parliament that such austerity measures are necessary to ensure the nation's survival. The government hopes to cut its budget deficit by some $32 billion. Union officials have expressed concern the measures will include tax increases and a wage freeze for government workers. They have called for a general strike on May 5. Politicians and investors are worried that economic problems could spread if Greece fails to pay back its debt. Those concerns grew in the past week when a key credit rating agency, Standard and Poor's, downgraded its credit ratings of Greece, Portugal and Spain.
