On this basis, the members of Syriza who fled the leftist party today vehemently criticized Tsipras, stating that the recent developments "will be recorded with black letters in the history of the country but also in the history of the Greek Left."
The 53 dissidents have already said that they will support the newly formed Popular Unity Party (Laiki Enotita). The leader of the new anti- bailout party is Panagiotis Lafazanis, who is the former Energy Minister of Greece and Syriza's co-founder. Lafazanis openly blasted Tsipras decision to accept the Eurozone Summit on July 12 and voted against all the austerity bills submitted to the Greek parliament for the new rescue agreement.
On Monday, Lafazanis was granted the maximum three-day mandate from President Prokopis Pavlopoulos to form a government after the main opposition conservative New Democracy leader Vagelis Meimarakis failed to form one. Considering the fast turnaround, Lafazanis is expected to fail since the deadline is today. As a result, Greeks will going back to the ballot box on September 20 to vote for a new government for the second time in eight months.

It's expected that after the forthcoming elections Lafazanis will become the regulator of the political developments, as he will be the main critic of the austerity program, especially if his party takes third place in the elections.
Currently, there are no credible opinion polls in Greece to gauge how the political landscape will shift after the elections. Most political analysts predict that the New Democracy Party and Syriza will compete for first place. Regardless, Lafazanis, will be an ardent political opponent of the new Greek coalition government.
In an exclusive interview with CNBC, Lafazanis discussed his political views. First and foremost, Lafazanis said he aims to abolish the bailout program and cancel austerity plans. As he explained, "The principles of the Popular Unity Party include the end of national subordination and the need to follow a new independent, sovereign and progressive course."
Top on the party's agenda is to restore salaries and pensions to levels before 2010, as well as nationalize banks and private monopolies. The Popular Unity leader is a former member of Greece's Communist Party, and is opposed to Syriza's transformation from a party of the radical left which seeks the extensive government intervention in the economy to a European socialist party which practices modern capitalism.
