The court also handed down a political activity ban that could permanently remove him from office if the ruling is upheld on appeal.
Legal Fallout and Political Ban in Istanbul
The latest court ruling stems from accusations that Imamoglu insulted a public official four years ago, as reported by Turkish media. During Friday’s proceedings, which he attended via video link from a high-security prison, Imamoglu dismissed the allegations as baseless and branded the verdict a scandal, according to the state broadcaster TRT. The case had previously gone through two separate acquittals before an appellate court ordered a retrial citing procedural errors.
Under the terms of the decision, if the two-year and one-month prison sentence becomes final, Imamoglu will formally lose his mayoral seat. In that event, Istanbul’s municipal council would receive the authority to select a new leader for the country’s economic and cultural hub. Opposition figures inside Turkey immediately condemned the verdict, characterizing the judicial process as politically motivated and designed specifically to sideline Erdogan’s strongest rival.
Escalating Crackdown on Opposition Leadership
Political tensions surrounding Istanbul’s municipal administration have intensified steadily since the opposition Republican People’s Party (CHP) captured the city hall in the 2019 local elections. Imamoglu successfully defended his seat in the subsequent 2024 municipal contests, reinforcing his status as a viable alternative to Erdogan’s long-standing rule. However, a sweeping wave of arrests in March 2025 targeted Imamoglu alongside numerous municipal staff members and CHP mayors across various Turkish municipalities.
Following those arrests, the legal pressure expanded into a cascade of investigations and criminal proceedings encompassing allegations of corruption, money laundering, and the formation of a criminal organization. Government officials in Ankara have consistently rejected accusations of political interference, maintaining that the Turkish judiciary operates independently.
International Reaction and Democratic Concerns
The ongoing legal maneuvers against Istanbul’s leadership have drawn sharp rebukes from Western capitals and international bodies. The German federal government, the European Parliament, and the European Commission have each characterized the removal and prosecution of Imamoglu as a substantial setback for democratic norms and the rule of law in Turkey.

While Imamoglu previously stood out as a prospective candidate to challenge Erdogan in a future presidential contest, the accumulation of ongoing trials, convictions, and administrative suspensions leaves his immediate political future uncertain.
