According to the Greek Efimerida Ton Syntakton newspaper, the first opinion poll released since Alexis Tsipras resigned last week show former prime minister's Syriza party in the lead before the snap elections to be held on Sept. 20.
The poll, which was carried out by ProRata interviewing a sample of 1,000 people, shows that the Syriza party has 23 percent support while the conservative New Democracy party has 19.5 percent.
Popular Unity which was formed by the former members of Syriza party was backed by 3.5 percent of those polled.
Independent Greeks, who were coalition partners with Tsipras in the government, got 2 percent support which is below the 3 percent threshold it needs to enter the parliament.
Tsipras resigned last week facing an uprising by some members of his party who opposed the austerity measures in the bailout reforms.
In his statement of resignation, he said that Greek public is supposed to process a new commission and he called for an early election.
"With your vote, you will decide who will lead Greece into this difficult but hopeful path forward. I will ask for the vote of the Greek people in order to govern and unfold our program," Tsipras said in his statement.
The bailout, which helps prevent Greece's exit from the euro currency, is the country's third in about five years.
Greece received the first 13 billion euros from its new bailout package allowing it to pay a debt of 3.2 billion euros to the European Central Bank after it was approved by relevant European parliaments.
However, in parliament vote to approve the bailout conditions, many lawmakers of anti-austerity Syriza voted against him and this led to split of his party, forcing Tsipras to resign and trigger early elections.
