Thousands of government supporters have gathered in celebration in Athens's main square, waving Greek flags and chanting "No, No" after returns show their side leading in Sunday's referendum.
Vendors have set up stalls to sell kebabs, sandwiches, whistles and Greek flags in Syntagma Square in front of Parliament.
Athens resident Yiannis Gkovesis, holding a large Greek flag, says "we don't want austerity measures anymore. This has been happening for the last five years and it has driven so many into poverty. We simply can't take any more austerity."
The 26-year-old Gkovesis says "if the Europeans really wanted Greece to stand on its feet, then they could have done so without imposing such harsh measures."
Supporters of Prime Minister Alexis Tsipras's SYRIZA party staged the rally two days after he drew massive crowds to his final campaign rally — also in front of parliament.
