Eskişehir's Tepebaşı Mayor Ahmet Ataç announced his resignation from the CHP, of which he has been a member since 1972, via social media.

Eskişehir Tepebaşı Mayor Ahmet Ataç announced on Saturday, August 8, through his social media account that he has resigned from the Republican People's Party (CHP). Ataç had been a CHP member since 1972 — that is, for 54 years.
Ataç stated that he will continue his political struggle under the banner of YENİ Party, founded by Muharrem İnce. In his statement, Ataç emphasized that he believes 'principles, not individuals and offices, should be the determining factor,' and said he will maintain his commitment to Atatürk's vision of a contemporary Turkey.
Ataç's departure is not merely a symbolic loss for the CHP; it represents the defection of a mayor who effectively governs the Tepebaşı district from opposition ranks. This rupture in a city where the CHP controls the metropolitan authority directly affects calculations for the 2028 local elections. YENİ Party has for the first time obtained a mayor-level position since its founding.
Eskişehir Tepebaşı Mayor Ahmet Ataç ended his 54-year CHP membership and joined Muharrem İnce's YENİ Party. The move strengthens opposition ranks in Eskişehir, where the CHP holds the metropolitan authority, and will reshape calculations for the 2028 local elections.
The loss of a long-serving mayor is reshaping political balance in Eskişehir and will influence how votes are distributed across the city in the 2028 elections. YENİ Party's gain of its first mayor represents the party becoming a genuine actor in local politics.
