The European Commission endorsed Greece's austerity plan on Wednesday but said Athens must take further steps to cut public sector wages to tackle the most severe debt crisis in the euro zone.
Following is a timeline of events since Prime Minister George Papandreou's socialist PASOK party won snap elections last October.

November 2009 - The new government pledges in its 2010 draft budget to save Greece from bankruptcy by cutting the deficit while keeping electoral promises to help the poor amid the economic crisis.
-- Final budget draft shows Greece aims to cut its budget deficit to 9.1 percent of GDP in 2010 to assure EU partners and markets it is serious about restoring fiscal health.
-- It also sees public debt rising to 121 percent of GDP in 2010 from 113.4 percent in 2009. EU forecasts on Greece for 2010 are worse, with the deficit seen at 12.2 percent of GDP and national debt rising to 124.9 percent of GDP, the highest ratio in the EU.
December 2009 -- S&P on December 7 puts the country's A- sovereign rating on negative watch.
-- On Dec 8, Fitch Ratings, which had cut Greece to A- when the government revealed the higher deficit, cuts Greek debt to BBB+ with a negative outlook, the first time in 10 years a ratings agency has put Greece below the A investment grade.
-- The next day, Papandreou says he is determined to win back the country's lost credibility.

Papandreou announces a 10 percent cut in social security spending in 2010. Says he will abolish bonuses at state banks and slap a 90 percent tax on private bankers' bonuses. Vows a serious fight against corruption and tax evasion, calling them the country's biggest problems.
-- He announces a drastic overhaul of the pension system in six months and a new tax system that will make the wealthier carry more of the burden. Greece says it now plans to cut its budget deficit to 8.7 percent of GDP this year.
-- Standard & Poor's cut Greece's rating by one notch on December 16, to BBB-plus from A-minus, saying austerity steps announced by Prime Minister Papandreou were unlikely to produce a "sustainable" reduction in the public debt burden.
-- Yield spreads between Greek and benchmark German 10-year bunds widened to an average 272 basis points on December 19, the widest in more than 8 months, as skeptical markets continue to sell Greek government bonds and stocks.
-- Moody's cuts Greek debt to A2 from A1 on December 22 over soaring deficits, the third rating agency to downgrade Greece, but still two notches above that of Fitch and S&P. The spread between 10-year Greek and German Bunds tightens after the downgrade.
