Athens , Greece ( CNN ) -- Three of the top four vote-getters in Sunday 's parliamentary elections in Greece will meet Tuesday at the presidential palace to form a coalition government , an official with the socialist party Pasok told CNN . The official spoke not for attribution because the talks were at a critical juncture . `` As wide as possible cooperation ... should happen at the latest tomorrow evening , '' said Evangelos Venizelos , head of the Pasok Party , which placed third . The center-right New Democracy Party took first place in the vote . Its candidate , Antonis Samaras , has three days to cobble together a government . `` There should be government of national salvation with as many parties as possible , '' Samaras told reporters . Democratic Party of the Left 's leader , Fotis Kouvelis , held talks Monday that the New Democracy leader described as `` constructive . '' The party 's platform has supported the bailouts while seeking to renegotiate the terms . With almost all ballots counted , New Democracy had won nearly 30 % of the vote , the Interior Ministry said . That gives the party 129 seats in the country 's 300-seat parliament , forcing it to seek other coalition members from the fragmented field to form a majority . Alexis Tsipras , the leader of the leftist Syriza party , which came in second , met with Samaras but said Monday he would not back a coalition . `` History and the people will judge them by their results , '' Tsipras said of the parties backing the existing bailout deal with the creditors who are keeping Greece afloat . `` Shortly we will be vindicated . '' What will Greek elections mean for the country 's future ? He said his party 's nearly 27 % showing had forced Greek leaders to realize the bailout is `` nonviable , '' and said Syriza would press as a member of the opposition for the bailouts to be scrapped . An official with Syriza told CNN that no one from the party was planning to attend the meeting . Syriza , which campaigned against the terms of the bailout , got 71 seats . Pasok , which long dominated Greek politics , won 33 . Four smaller parties took fewer than two dozen seats each . The vote was widely seen as a referendum on whether Greece should remain in the euro , the currency used by 325 million people across 17 countries in Europe . The possibility of a `` no '' vote roiled world markets , with some analysts warning that the collapse of the euro would cost $ 1 trillion . Asian markets reacted positively to the election results , while European and U.S. markets were mixed . Samaras said he would build a government of `` parties that believe in the nation 's European orientation , that believe in the euro . '' But he acknowledged that government budget cuts forced on the country by international lenders have caused suffering among Greeks . A wild election weekend for Greece , France and Egypt . The new government will have to make changes `` in order for the Greek people to escape the torturous reality of unemployment and unbelievable difficulties that every Greek family faces today , '' Samaras said after meeting with the president . He faces a new round of coalition talks , six weeks after a previous election that failed to produce a government . International bailouts have kept Greece from defaulting in the face of an ongoing recession and low tax revenue , but lenders have demanded hugely unpopular government budget cuts in exchange . Eurozone finance ministers praised the election results , `` which should allow for the formation of a government that will carry the support of the electorate to bring Greece back on a path of sustainable growth . '' Some observers had predicted that efforts to renegotiate the bailout could lead to a run on Greek banks and deeper misery . The future of Europe : 3 scenarios . `` Do n't underestimate the capacity of the Greek people to rise to the occasion , '' Petros Doukas , a former New Democracy lawmaker and deputy finance minister , told CNN . `` What 's very clear is the Greeks today voted , including those that voted for Syriza , in favor of the euro and the European Union , '' Doukas said . He predicted that Greece could negotiate better terms with its creditors , who understand `` that you can only squeeze so much so fast out of a country and out of its people . '' Greeks have been suffering under painful austerity measures , high unemployment and a long-running recession . The country must identify additional budget cuts by the end of June to be considered compliant with the terms of its bailout . German Chancellor Angela Merkel , Europe 's powerful advocate for balancing budgets to build a strong basis for economic growth , had urged Greeks not to walk away from the international loan deals . `` We will stick to the agreements . That is the basis on which Europe will prosper , '' she said Saturday . As economic crisis bites , Greece 's children pay the price .
