Greek PM George Papandreou has said he is ready to drop a proposed referendum on the country's eurozone bailout deal.
He said he was focusing on talks to secure opposition support in parliament which would make the vote unnecessary.
His announcement of a referendum angered European leaders and sent shockwaves through its markets.
The main opposition has called for his resignation and snap elections, and walked out of a debate in parliament ahead of a confidence vote on Friday.
Mr Papandreou's Socialist party (Pasok) holds a slim majority in parliament, 152 out of 300 seats.
New Democracy leader Antonis Samaras said Mr Papandreou had "nearly destroyed Europe and the euro" with his call for a referendum.
Mr Papandreou told MPs it would be irresponsible for the government to resign but that he was "not clinging on to any chair".
He said talks with the opposition on forming a "broader scheme" - apparently meaning a coalition government - should start immediately.
The BBC's Mark Lowen, in Athens, says that the prime minister hopes that if the threat of a referendum fades he can yet steer the country through the crisis.
The EU bailout deal, agreed last month, would give the heavily indebted Greek government 130bn euros (£111bn; $178bn) and it imposes a 50% write-off on private holders of Greek debts, in return for deeply unpopular austerity measures.
EU leaders say Greece cannot get bailout cash until there is clarity on the referendum issue.
Responding to the recent developments in Greece, French President Nicolas Sarkozy said that after talks with Mr Papandreou on Wednesday there was more of a sense of urgency in the country.
"I think the message that was sent to the entire Greek political class yesterday by Germany and France together has helped in a sort of realisation of how things might develop and in Greece they have realised this," he told reporters at the G20 summit in
Finance Minister Evangelos Venizelos, addressing Pasok MPs earlier, said Greece must say it was not holding a referendum.
He said Greece must do everything it can to reassure its international partners it will immediately implement the Eurozone bailout deal.
Mr Papandreou told the gathering the referendum on the deal was never an end in itself, and there were two other choices - an election, which he said would bankrupt the country, or a consensus in parliament.
"If we had a consensus we wouldn't have to go to a referendum," he said.
"If the opposition is willing to negotiate then we are ready to ratify this deal and implement it."
