The Republican People’s Party (CHP) managed to achieve a noticeable electoral victory against the ruling Justice and Development Party (AKP) in the latest local elections that were held on 31 March 2024. However, the joy of victory did not last long, as the Mayor of Istanbul, Ekrem İmamoğlu, was arrested for corruption charges before being ousted from his position as the Mayor of Istanbul. The investigation into corruption charges revealed that the CHP leadership elections held on 4–5 November 2023, which resulted in the election of Özgür Özel as the party’s leader, might have involved illegal activities that could have jeopardised the transparency of the outcome. As a result, the Turkish judiciary is investigating this issue at the moment. On Monday, Sept. 15 2025, a Turkish court in Ankara held a hearing in a case questioning the legitimacy of the CHP’s 2023 leadership election (the 38th Congress), alleging irregularities like vote-buying, meaning that the outcome of the CHP leadership elections may be invalidated. If it happens, the impact on the CHP and electoral map in Turkey could be massive.
