Worries over second bailout for Greece
There are concerns that Greece may need to be bailed out for a second time.
It follows speculation that the troubled country is considering leaving the euro and readopting its old currency.
The Greek Prime Minister George Papandreou has denied these claims while the head of the Eurozone Finance Ministers Jean Claude Juncker dismissed them as "stupid".
But a second bailout may now be on the cards amid concerns the country might not be able to access the capital markets to repay its debts.
The British Chancellor of the Exchequer George Osborne has suggested Greece might need further help, but he doesn't think it will have to default on its loans.
