With more than 20% of votes counted, results from the Greek referendum suggest voters have rejected the terms of an international bailout.
Results published by the interior ministry showed about 60% of those whose votes had been counted voting “No”, against some 40% voting “Yes”, the BBC reports.
Greece’s governing Syriza party campaigned for a “No”, saying the bailout terms were humiliating.
The “Yes” campaign warned this could see Greece ejected from the eurozone.
Senior European officials had also said that a “No” would be seen as a rejection of talks with creditors.
But Greek government officials have insisted that a “No” vote would strengthen their hand and that they could rapidly strike a deal for fresh funding in resumed negotiations.
Greek banks would reopen by Tuesday, they say.
In the meantime, Greek government spokesman Gabriel Sakellaridis told state TV that Athens is planning to resume the talks with the Troika., rt.com reports.
“The negotiations which will start must be concluded very soon, even after 48 hours,” Sakellaridis said, “We will undertake every effort to seal it soon.”
Proponents of the “Yes” vote argued that a “No” vote may lead to Greece’s exit from the Eurozone, and potentially the EU.
The talks between Greece and the Troika of international creditors – the EU, the European Central Bank and the International Monetary Fund – have stalled since June, after the Eurogroup declined to prolong a financial aid program for Greece or delay payments on earlier debts.
Greece, which has been in crisis since 2009, was supposed to make an IMF loan payment of EUR 1.6 billion by June 30 but failed to do so. It is required to make another major payment of EUR 3.5 billion to the ECB on July 20.
