Panos Skourletis, energy minister in the Syriza-led government which resigned last week, also said the nation must avoid deadlock leading to a second round of elections, a scenario that politicians are already debating even though a first round has yet to be called.
Syriza, which during its seven months in power took Greece to the brink of financial collapse and exit from the euro, is projecting confidence, although it remains beset by internal divisions even after it formally split last week.
“I believe that an absolute majority in parliament for Syriza is achievable,” Skourletis told Mega TV.
He also played down the possibility of doing a post-election deal with the main pro-bailout groups, the conservative New Democracy, centrist To Potami or the PASOK socialists.
“For collaborations to be politically credible, they must be based on an existing convergence of programmes, a common ground,” he said.
“I do not see this political credibility with the forces of New Democracy, Potami or PASOK.”
Greece’s president has tasked two opposition parties with trying to form a new government after prime minister Alexis Tsipras quit last Thursday, hoping to avoid an election only seven months after the last one brought Syriza to power.
With parties deeply divided over the bailout, Greece’s third since 2010, and its tough conditions, New Democracy has already failed to find coalition partners.
Now Popular Unity, the far-left breakaway from Syriza, is going through the motions.
Its leader, Panagiotis Lafazanis, has already admitted defeat and is using his three-day presidential mandate merely to win air time for his anti-bailout message.
Once his mandate expires tonight, President Prokopis Pavlopoulos is expected to make one final attempt to achieve a compromise among the parties.
As this is also nearly certain to fail, he will then appoint a caretaker premier and call elections within 30 days.
Greeks are starting to worry the election might fail to end the paralysis just as the country is supposed to be implementing the bailout measures, and a second round must be held, as in 2012.
Skourletis opposed such a scenario.
“We must avoid this. People know this and will vote in such a way so that we do not end up in a jam,” he said.
Whether Syriza’s show of confidence is justified is unclear.
No opinion poll has been published since July 24, well before Tsipras resigned and Syriza split.
