Representatives from the troika of international lenders arrive in Greece today to assess its progress towards reducing its huge debts. They must decide whether Greece is eligible to receive 31.5 billion euros, the last tranche of a 130 billion euro aid package agreed in March. Athens is behind in its plans to cut spending and debt because its economy is shrinking faster than forecast. The Greek prime Minister is expected to ask for more time to repay its loans.The International Monetary Fund (IMF), European Central Bank (ECB) and European Commission (EC) make up the troika. The IMF said it was supporting Greece in overcoming its economic difficulties and would work with the country to get it back on track. Greece has promised to reduce its budget deficit below 3 per cent of annual national income as measured in Gross Domestic Product (GDP) by the end of 2014. At the end of last year, Greece's overspend was equivalent to 9 per cent of GDP in 2011.
