More than 800 party delegates submitted petitions calling for a special congress to elect a new leader, according to a party source, surpassing the threshold required under CHP bylaws to convene a gathering within 45 days.

The move follows a controversial ruling by an Ankara court in May that annulled the CHP’s 2023 leadership election over allegations of vote-buying and restored Kilicdaroglu to the party leadership.

The decision triggered strong opposition within the CHP and intensified tensions between rival factions of the party. Critics argued that the court ruling interfered with the internal affairs of Turkiye’s largest opposition movement at a time when it has been gaining political momentum.

Ozgur Ozel, who emerged as a prominent critic of President Recep Tayyip Erdogan during his tenure as party leader, has repeatedly rejected Kilicdaroglu’s reinstatement and called for a fresh vote, arguing that the party cannot be governed by what he describes as an imposed leadership.

Political analysts expect a fierce internal contest in the coming weeks. While Ozel’s supporters have succeeded in forcing the issue onto the party agenda, observers say Kilicdaroglu is likely to resist efforts to organize a rapid leadership vote and could seek procedural or legal avenues to delay the congress.

The dispute has further deepened divisions within a party already grappling with years of internal debate over strategy, leadership and electoral performance.

The CHP, founded by the republic’s founder Mustafa Kemal Ataturk, has recently strengthened its position against Erdogan’s ruling Justice and Development Party (AKP), particularly after securing significant victories in the 2024 local elections.

Opposition figures have accused authorities of pursuing politically motivated actions against the CHP in an effort to weaken its growing electoral appeal. Those accusations intensified following the court decision and subsequent police operations at party headquarters.

Kilicdaroglu led the CHP for more than a decade before being voted out at the party congress in 2023. His departure followed a closely contested presidential election in which he lost to Erdogan, prompting widespread calls within the party for leadership renewal.

The outcome of the proposed extraordinary congress is likely to shape the future direction of the CHP and could influence the broader balance of power in Turkish politics as opposition parties seek to challenge Erdogan’s long-standing dominance.

With rival camps now preparing for a potentially decisive confrontation, the CHP faces one of the most consequential internal battles in its recent history.
