The appointment of Gürsel Tekin, former Deputy Chairman of the Republican People's Party (CHP), as trustee to replace Ozgur Celik, the CHP Istanbul Provincial Chairman, sparked widespread outrage. On September 7, 2025, police intervened in protests that began in front of the CHP Istanbul Provincial Headquarters, which had been cordoned off by police following a governor's decision, and some individuals were detained. CHP members state that this incident constitutes a formal coup, following the March 19 protests that began with the arrest of Istanbul Metropolitan Mayor Ekrem Imamoglu.
