Accusations pile up in former Istanbul mayor’s corruption trial

The brief

Ekrem İmamoğlu is the former mayor of Istanbul and a presidential candidate for the Republican People’s Party, later its spin-off New Party. He was arrested last year and remains in custody. Prosecutors describe the case as involving an “Imamoğlu criminal organization.” The allegations center on municipal business. Prosecutors say officials and associates sought bribes, manipulated tenders, and used municipal powers to pressure companies. Witnesses described alleged demands for campaign money, “charity” cheques, donations, and payments linked to permits. Several defendants are municipal employees or subsidiary managers. The case is still at the trial stage, so these are allegations, not proven findings. This week, witnesses including Gürgen, Uğur Kemal Gökbulut, Sefer Kocabaş, Ilker Aydın, and Metin Karakoç gave evidence. Imamoğlu is held with 46 other defendants, while 436 defendants face trial overall. Prosecutors seek thousands of years in prison.

01

Who is Ekrem İmamoğlu, and what allegations are prosecutors presenting against him and other defendants?

Ekrem İmamoğlu is the former mayor of Istanbul and a presidential candidate for the Republican People’s Party, later its spin-off New Party. He was arrested last year and remains in custody. Prosecutors describe the case as involving an “Imamoğlu criminal organization.”

The allegations center on municipal business. Prosecutors say officials and associates sought bribes, manipulated tenders, and used municipal powers to pressure companies. Witnesses described alleged demands for campaign money, “charity” cheques, donations, and payments linked to permits. Several defendants are municipal employees or subsidiary managers.

The case is still at the trial stage, so these are allegations, not proven findings. This week, witnesses including Gürgen, Uğur Kemal Gökbulut, Sefer Kocabaş, Ilker Aydın, and Metin Karakoç gave evidence. Imamoğlu is held with 46 other defendants, while 436 defendants face trial overall. Prosecutors seek thousands of years in prison.

02

What is corruption in public office, and how do bribery and tender-rigging typically work?

Corruption in public office means using government authority for an improper private or political benefit. A bribe is money, a gift, or another advantage offered or demanded in exchange for official action. Tender-rigging means secretly shaping a public contract so a favored bidder wins, rather than allowing genuine competition.

The usual mechanism is leverage. An official may delay a permit, payment, approval, or contract unless a company pays. In a rigged tender, requirements, information, scoring, or competitors may be manipulated. The article describes alleged demands for cheques, donations, and payments tied to municipal decisions. It does not detail a specific rigged tender process.

These practices can raise costs and reduce trust. They may push honest businesses out and reward connections over quality. The hearings have not established guilt. The witnesses’ accounts are allegations presented in court, while prosecutors are pursuing the case against İmamoğlu and hundreds of other defendants.

03

How large is this case, in terms of defendants, people held in custody, and prison sentences prosecutors are seeking?

The case is unusually large by the figures given in the article. A total of 436 defendants are being tried. They include İmamoğlu, municipal bureaucrats, and others accused of connections to the alleged corruption network. The scale helps explain why hearings involve many witnesses, plaintiffs, and co-defendants.

İmamoğlu was arrested last year and has been held in custody with 46 other defendants. That means the article identifies 47 people in custody in this group, counting İmamoğlu. Most of the remaining defendants were released under judicial control, a court-imposed form of supervision while proceedings continue.

Prosecutors are seeking thousands of years in prison for İmamoğlu and fellow defendants. The article does not give one precise total or individual sentence request. These figures describe the prosecution’s case, not final convictions. The hearings were continuing at the massive courthouse-prison complex in Silivri, with more testimony expected before the week closed.

04

Why do municipal officials have the power to affect construction permits, public contracts, fines, and payments to companies?

Municipal governments regulate many local activities because construction and business projects affect land use, roads, safety, services, and city planning. Their departments may review applications, issue permits, inspect work, collect fees, enforce rules, and authorize payments. Municipal subsidiaries may also manage services or public contracts.

That authority creates pressure points. In the article, Gökbulut said a deputy mayor demanded cheques before issuing construction permits. Kocabaş said officials allegedly fined a shopping mall after its owners refused a parking-garage bribe. Aydın said apartment and commercial permits were withheld until a company agreed to pay.

Officials are supposed to apply rules consistently and document decisions. The article does not establish whether every allegation is true, or explain the precise legal powers of each official. The broader lesson is that permit, enforcement, contracting, and payment decisions can affect a company’s ability to build, operate, and recover money. Oversight is therefore important.

05

What consequences can alleged bribery and permit manipulation have for businesses, public finances, construction projects, and city residents?

Alleged bribery can harm businesses immediately by adding hidden costs, delaying approvals, or blocking projects. Companies may have to borrow longer, abandon investments, or pay to receive services they should obtain through lawful procedures. Public finances can also suffer when contracts or approvals favor connected parties rather than value, quality, or fair competition.

The article gives several concrete examples. A pharmaceuticals company’s construction project remained incomplete after permits were withheld, according to Ilker Aydın. He said the company was asked for $5 million and later agreed to pay $3.5 million. Kocabaş also alleged that a mall received irrelevant fines after refusing a payment.

For residents, delays can mean unfinished housing, commercial space, or facilities, while higher costs can affect prices and local economic activity. These outcomes are possible consequences, not findings established by the trial. The article records witness testimony and prosecution claims; the court must determine what happened and who bears responsibility.

06

What safeguards—such as competitive tendering, financial oversight, and independent courts—are meant to prevent officials from demanding improper payments?

Safeguards work by separating decisions, exposing transactions, and creating consequences for abuse. Competitive tendering lets qualified bidders compete under published rules. Financial oversight checks whether money is spent lawfully. Independent courts can review evidence without taking instructions from the officials involved.

Other protections include written permit criteria, deadlines, public contract records, conflict-of-interest disclosures, whistleblower channels, audits, and approval by more than one official. Payments should move through traceable systems, not informal requests for cheques or “donations.” These measures address the kinds of alleged conduct described in the article, including demands linked to permits, approvals, and municipal payments.

No safeguard is automatic. Oversight bodies need access to records and freedom to investigate. Courts must assess testimony fairly and protect defendants’ rights. The article does not describe which controls operated in Istanbul or whether they failed. It shows why transparent procedures matter: several witnesses alleged that companies faced pressure when seeking ordinary municipal decisions.

07

How do local governments normally regulate land use and spend public money, and why does that create opportunities for both public service and abuse?

Local governments organize city services and manage decisions close to residents. In general, they regulate land use through planning rules, permits, inspections, and enforcement. They also spend public money on construction, maintenance, services, and municipal companies. These powers allow cities to coordinate growth and deliver projects.

The opportunity for abuse comes from discretion and dependence. A company may need a permit before building, approval before opening, or payment after completing work. Officials may control information, timing, inspections, or access to contracts. In the article, witnesses alleged that municipal actors linked cheques, donations, and bribes to permits, approvals, payments, and campaign support.

These allegations do not show that normal municipal regulation is improper. Clear rules, records, competitive procurement, oversight, and review are meant to keep public authority serving residents. The article focuses on testimony in an ongoing trial, not on a complete description of Istanbul’s legal system. Its central issue is whether official powers were allegedly converted into private leverage.
