Greece's latest offer to creditors involves a proposal to tap Europe's bailout fund — the European Stability Mechanism, a pot of money with about half a trillion euros set up to help countries in need. The prime minister's office said the proposal was "for the full coverage of [Greece's] financing needs with the simultaneous restructuring of the debt.”
For the last several months, Greek and other European officials have been negotiating on the terms of extending the current bailout arrangement. But Athens, which feels that the terms of previous loans were far too onerous and crippled Greece’s economy, changed tack on Tuesday and proposed a different loan agreement.
But the request for a new bailout arrangement was linked to a last-minute Greek request on Tuesday for an extension of loans to cover the country’s increasingly dire financial prospects. That extension request was rejected late on Tuesday.
Dijsselbloem, however, said the finance ministers would study the new proposal and that they would hold another conference call Wednesday.
European officials and Greek opposition parties have been adamant that a "No" vote in Sunday's referendum would mean Greece will leave the euro and possibly even the EU, though it wasn't clear whether there is a legal recourse for its dismissal.
The Greek government says this is scaremongering, and that a rejection of creditor demands will mean the country is in a better negotiating position.
In Athens, more than 10,000 "Yes" vote supporters gathered outside parliament despite a thunderstorm, chanting "Europe! Europe!"
Most huddled under umbrellas, including Athens resident Sofia Matthaiou.
"I don't know if we'll get a deal. But we have to press them to see reason," she said, referring to the government. "The creditors need to water down their positions, too."
The protests came a day after thousands of government supporters advocating a "No" vote held a similar demonstration.
On Monday, European Commission President Jean-Claude Juncker made a new offer to Greece. Under that proposal, Tsipras would need to accept the creditors' proposal that was on the table last weekend. He would also have to change his position on Sunday's referendum.
Commission spokesman Margaritis Schinas said the offer would also involve unspecified discussions on Athens's massive debt load of over 300 billion euros, or around 180 percent of GDP. The Greek side has long called for debt relief, saying its mountainous debt is unsustainable.
A Greek government official said Tsipras had spoken earlier in the day with Juncker, European Central Bank chief Mario Draghi and European Parliament president Martin Schulz.
