Ever since George Papandreou, the Greek prime minister, came to power two years ago, he has struggled to manage country’s balance sheets.
And last year, the worst came to the fore: Greece said it was not in a position to pay salaries to its government employees.
Papandreou managed to convince IMF and EU to bail Greece out of the financial morass, but it came with lot of conditions.
The series of tough austerity measures that Papandreou’s government announced forced people to come out on the streets, leading to a plunge in his popularity.
Here are the key moments since May last year:
November 16 - Prime Minister Lucas Papademos's coalition wins large majority for his austerity plans to speed up long-term reforms and secure a massive new bailout deal involving banks and rescue creditors.
November 11 - Lucas Papademos is sworn in as Greece's interim prime minister. His newly appointed coalition cabinet includes Evangelos Venizelos, retaining the key position of finance minister.

Papandreou tells parliament he will talk with parties about forming a wider coalition party and is ready to discuss who will lead a new government.
November 3 - Evangelos Venizelos, the Greek finance minister, comes out against a referendum, saying Greece's euro membership was a historic achievement and "cannot depend on a referendum".
Papandreou defies demands he resign over his decision to hold a referendum and calls instead for his party to unite for a confidence vote in the government.
Antonis Samaras, the opposition New Democracy Party leader, calls on Papandreou to resign and demands snap elections in six weeks.
November 2 - Papandreou wins cabinet backing to hold a referendum on a 130bn-euro ($178bn) bailout package.
