A leadership election was held on 24 November 2024. The winner was Sokratis Famellos, an MP of Syriza and former leader of the parliamentary group. In second place, with a small gap to the winner, was the MP from Chania, Pavlos Polakis, who said that he did not want a second round.
These elections — the most tumultuous in Syriza's history — were marked by the decision of the party's supreme bodies to reject the possibility of former Syriza president Stefanos Kasselakis running, a decision that caused fierce disputes among the party's executives and grassroots members. ;br ;
About 70,000 voters who were already registered members of the party voted (in the immediately preceding elections 147,000 people who could register on the same day had voted), a figure that SYRIZA officials described as a success under the circumstances.
Background.
Previous leadership election.
After Alexis Tsipras resigned as the President of Syriza, in June 2023 a leadership election was called.
On the first round of the elections, Stefanos Kasselakis and Effie Achtsioglou made it to the second round, with 44.9% and 36.2% of the votes respectively, Euclid Tsakalotos reached the third spot with 8.9%, Nikos Pappas followed with 8.7%, and finally Stefanos Tzoumakas got 1.3%.
On the second round, Kasselakis won over Achtsioglou, 56% to 44%.
Internal party crisis.
After the election of Stefanos Kasselakis, the criticism and questioning of his political actions by party members and MPs intensified. Soon, the internal opposition groups "Umbrella" and "6+6" left the party, founding, some time later, New Left.
In February 2024, the 4th Congress of the party was held. Stefanos Kasselakis announced extraordinary internal party elections for the election of the president, with Olga Gerovassili announcing her candidacy. In the end, the elections did not take place and tensions were averted in view of the upcoming European elections.
In the European elections, Syriza maintained second place, but with a lower percentage (14.92%) and elected four MEPs. This, combined with sudden replacements of party individuals, changes to the party structure and the suspension of the daily edition of I Avgi, exacerbated the discontent within the party.
The questioning of Stefanos Kasselakis culminated in the meeting of the Central Committee of Syriza, on 7 September, during which 100 members submitted a motion of no confidence against the party president, which was adopted by 163 votes to 120, removing the president, Stefanos Kasselakis, and triggering a leadership election. 
On 11 September, the date of the election was effectively decided in a meeting of the political bureau of the party, with the final decision pending upon the meeting of the central committee. Before the elections, on 1-3 November, an extraordinary congress will take place, where all the candidacies will be presented. On 12 October, the Central Committee of the party decided that Kasselakis cannot be candidate. On 8 November, after the new rejection of his candidacy by party's conference, Kasselakis left Syriza and announced the foundation of a new party. A day later, the party's Extraordinary Congress voted to confirm the candidacies of Polakis, Famellos, Farantouris and Gletsos.
