The operation followed a decision by an appeals court on Thursday that annulled the results of the CHP’s 2023 party congress and removed party leader Ozgur Ozel from office, citing irregularities in the internal election process.

The court reinstated former CHP chairman Kemal Kilicdaroglu, who led the opposition against President Recep Tayyip Erdogan in the 2023 presidential election but was defeated at the polls.

A Reuters witness said riot police used tear gas and forced entry into the CHP headquarters as supporters and party officials attempted to resist efforts to implement the court order. Images from the scene showed party supporters gathering outside the building in central Ankara while security forces secured the area.

The confrontation marked the latest development in a growing dispute over the leadership of the CHP, Turkey’s largest opposition party and the principal challenger to Erdogan’s ruling political bloc.

Ozel rejected the court ruling and described it as a “judicial coup,” arguing that the judiciary was interfering in the internal affairs of the opposition. He vowed to challenge the decision through legal channels and pledged to remain at party headquarters while pursuing appeals.

On Saturday, Ozel called for a new party congress to be convened as quickly as possible in an effort to resolve the leadership dispute through another internal vote.

Kilicdaroglu, meanwhile, said a congress would be organized at what he described as an appropriate time, signaling a different approach to managing the transition following the court decision.

Despite the ruling removing him as party chairman, CHP lawmakers on Saturday elected Ozel as leader of the party’s parliamentary group, underscoring continued support for him among many elected party representatives.
The leadership battle comes at a sensitive moment for Turkish politics, with the CHP seeking to maintain unity after years of internal debate over strategy and leadership following Erdogan’s victory in the 2023 presidential contest.
The court decision and subsequent police operation are likely to deepen tensions between the opposition and the government, with CHP officials continuing to argue that judicial institutions are being used to influence political outcomes, an accusation authorities reject.

State-run Anadolu Agency⁠ reported that prosecutors issued arrest warrants for 30 suspects linked to alleged corruption involving municipal subsidiaries and public tenders. Twenty-nine suspects were detained, while one individual was reported to be abroad.

According to a statement cited by prosecutors, the investigation concerns the alleged “activities of a criminal organization established under the leadership of Ekrem Imamoglu.”Authorities accuse the suspects of manipulating public procurement processes through companies affiliated with the Istanbul municipality.

Imamoglu, who has been imprisoned for more than a year, is currently standing trial alongside 413 co-defendants. Prosecutors allege he directed a large criminal network operating within the municipality. If convicted on all charges, he could face cumulative prison sentences totaling 2,430 years under Turkish law.

The Istanbul mayor and his political allies deny the accusations and argue the investigation is politically motivated, accusing Erdogan’s government of attempting to sideline one of the country’s most prominent opposition figures ahead of the 2028 presidential election.

Imamoglu emerged as a major national challenger to Erdogan after securing repeated election victories in Istanbul, Türkiye’s largest city and economic hub. Opposition parties have increasingly described the legal proceedings against him as part of broader pressure on dissenting political voices and municipal administrations controlled by the opposition.

The Turkish government has repeatedly denied accusations of political interference in the judiciary, maintaining that courts operate independently and investigations are conducted according to the law.
