Financial markets have fallen on investors' concerns about the impact of Greece's economic crisis.

To avoid the government defaulting on its debts, George Papandreou must pass new spending cuts and sell-offs of state property to receive new bail-out funds from the European Union and International Monetary Fund.

There have been reports that Mr Papandreou may seek to replace his finance minister, George Papaconstantinou, the main architect of hugely unpopular budget cuts.
The crisis comes amid a backdrop of soaring unemployment, with new figures on Thursday showing that the jobless rate rose to 15.9% in the last three months, up from 14.2% for the same quarter last year.
