İmamoğlu arrest sends shockwaves through Türkiye

The detention of Ekrem İmamoğlu, the Mayor of Istanbul Metropolitan Municipality, has sent shockwaves through Turkish society. He was snatched from his bedroom at the break of dawn on Wednesday in an operation that involved more than 400 police officers. At least 106 other people were also detained in the dragnet, with more arrests expected.

Among the others detained are the mayors of Şişli and Beylikdüzü in Istanbul, members of the main opposition party, CHP (The Republican People's Party). Prominent journalist İsmail Saymaz and famous pop singer and composer Ercan Saatçi were also detained—the charges: aiding the overthrow of the government.

The recent arrests were a culmination of weeks of detentions and investigations of mayors, municipal council members, and CHP members, as well as directors of artists' agencies, industrialists, journalists, and other political party leaders. Some have been detained for their statements regarding the economy, others on corruption charges, and some for participating in the Gezi Park protests in 2013.

The latter—which saw waves of demonstrations and civil unrest that started in İstanbul and spread to the rest of the country—remains a sore point for President Recep Tayyip Erdoğan and his AKP (Justice and Development Party).

Given İmamoğlu’s growing prominence in Turkish politics, it became increasingly apparent that he was the ultimate target of the ongoing crackdown. Within this context, his arrest isn’t entirely surprising. It followed a sustained government campaign against him—especially the attorney general’s probe into the validity of his university diploma from Istanbul University, recently revoked 31 years after he graduated.

The allegations about İmamoğlu's diploma surfaced following claims made to CİMER—the Presidential Communication Centre system allowing Turkish citizens to field their complaints and comments—upon which the Istanbul Chief Public Prosecutor's Office launched an investigation on 22 February 2025 on charges of “forgery of official documents”.

The Dean of the Faculty of Business Administration at Istanbul University, who had previously concluded in his report that there was “no irregularity” regarding İmamoğlu's diploma, resigned from his post a few days ago, citing “fatigue from long-term management and the recent process”. But CHP leader Özgür Özel said he resigned under government pressure to rescind his report.

Growing popularity

First serving as mayor of the Beylikdüzü district in Istanbul, İmamoğlu went on to win the hairsplitting Istanbul mayor election of 2019 against his AKP rival by only 13,000 votes. But AKP objections were taken to the Supreme Election Board, which annulled the election and called for another round.

İmamoğlu was likely to run against Erdoğan in the next presidential elections, and his candidacy was expected to be announced on 23 March

However, in the second round, he managed to get even more votes—boosting his margin from 13,000 to 806,014 votes and dealing the AKP a resounding electoral defeat. He ran again as a CHP candidate in the 2024 local elections and won with 51.1% of the vote—1.1 million more than his AKP rival.

As things currently stand, İmamoğlu can no longer run in elections because candidates must have a valid university degree according to Article 6 of the Election Law. But interestingly enough, he wasn't charged with having a fake degree—instead, he is accused of being the leader of a criminal organisation and also aiding the terrorist PKK group by granting favours to its members and sympathisers.

Because the alleged crimes are of an organised nature, the government can legally appoint a trustee to the Istanbul metropolitan municipality, which essentially means it can appoint anyone it wishes to replace him as mayor. İmamoğlu has the right to appeal to the Administrative Court and then to the Council of State, and his lawyers are expected to do so at the opportune time.

Protest ban defied

His arrest was accompanied by a four-day protest ban—between March 19-23—as well as a ban on press conferences. Subway and bus service routes have been redirected, and social media platforms restricted. These measures mean that Istanbul is effectively under martial law, with the clear aim to prevent İmamoğlu's supporters from taking to the streets. But already on Wednesday, people poured into the streets in defiance.

Eliminating a political threat

İmamoğlu was likely to run against Erdoğan in the next presidential elections in three years' time, and his candidacy was expected to be announced on 23 March. This gives credence to claims—by CHP supporters and many others— that his arrest is political. İmamoğlu's growing popularity could very well pose a threat to Erdoğan's grip on power, thus the need to take him out of the competition.

Reaction to his arrest has already been resounding. Mansur Yavaş—Mayor of Ankara Metropolitan Municipality and widely seen as İmamoğlu's competitor within the CHP—called his detention unlawful and undemocratic and says he won't discuss his possible candidacy until the government ends its unlawful campaign against İmamoğlu.

Opposition parties have also reacted. The leader of the İYİP (Good Party) Müsavat Dervişoğlu, as well as some of the founders of the AKP who left the group to form their own political parties—Ali Babacan, who served as Deputy Prime Minister in charge of the economy, and Ahmet Davutoğlu who was foreign minister and prime minister for years before leaving the AKP—have all said the arrest and general crackdown were tantamount to a political coup.

On the back of the developments, the Istanbul Stock Exchange fell by 7-8% on Wednesday morning. A circuit breaker was applied, and trading was suspended for a second time in the afternoon. Rising political tensions and the subsequent economic fallout paint a bleak picture for the country in the days ahead.
