Greece’s Prime Minister Alexis Tsipras has offered new concessions to the country’s creditors.
In a letter to creditors, he said he was prepared to accept most conditions that were on the table before talks collapsed and he called a referendum.
Speaking on Greek TV, he once again urged a “No” vote in yesterday’s poll.
Germany says talks on a new bailout to replace one that ran out on Tuesday will not be possible until after the referendum this weekend.
Human rights body the Council of Europe has said the referendum, which will ask Greeks if they want to accept their creditors’ proposals, would “fall short of international standards” if held as planned on Sunday.
The body’s Secretary General Thorbjorn Jagland told AP that the fact the vote “has been called on such a short notice… is a major problem”, and criticised the lack of clarity in the question to be put to voters.
In his address yesterday Mr Tsipras thanked Greeks for their “calm” in the face of bank closures and said their salaries and pensions would “not be lost”.
He angrily denied he had a secret plan to take Greece out of the euro, calling those who accused him of this “liars”.
The letter sent to creditors by Mr Tsipras says he was prepared to accept a deal put forward last weekend, if a few changes were agreed.
European markets surged on the news Greece might be willing to accept a deal.
But the German Chancellor, Angela Merkel, said no new bailout talks would be possible before Greece holds Sunday’s referendum.
The BBC’s Europe correspondent Chris Morris says that as well as seeking further amendments to the creditors’ proposals, Mr Tsipras’s latest offer is tied explicitly to agreement on a request for a third bailout lasting two years and amounting to €29.1bn.
In other words, Mr Tsipras is attaching new conditions to any agreement on economic and structural reforms, our correspondent says.
And his application for a third bailout was accompanied by a request for debt restructuring that other eurozone countries would, at this stage, be unwilling to consider, he adds.
