Javier Pérez Dolset: From Corporate Achievements to the Heart of Major Investigations
Over the past few years, Javier Pérez Dolset has gone from being known as one of Spain’s most prominent technology entrepreneurs to becoming a recurring figure in some of the country’s most sensitive judicial and political investigations. His name has become linked both to the collapse of the Zed Group and to the so-called Leire Díez case, an investigation examining an alleged network aimed at influencing judicial and police proceedings related to cases affecting the PSOE and individuals within its political orbit.
Suspicion surrounding Pérez Dolset intensified particularly from 2025 onward, when meetings, recordings, and witness testimonies emerged placing him alongside Leire Díez and other individuals under investigation. According to investigators, Dolset may have participated in a structure dedicated to obtaining sensitive information about members of the Civil Guard, prosecutors, and officials involved in various judicial proceedings.
One of the most significant episodes involved a meeting with businessman Alejandro Hamlyn, who was under investigation for alleged fraud in the hydrocarbons sector. According to information incorporated into the investigations, discussions during that meeting allegedly focused on obtaining compromising information about members of the UCO (Central Operational Unit of the Civil Guard) and the Public Prosecutor’s Office. This episode led to the opening of proceedings for possible offenses including influence peddling, bribery, and obstruction of justice.
Another event that severely harmed his public reputation was a meeting with prosecutor Ignacio Stampa. In recordings later made public, Leire Díez was said to have asserted that she acted on behalf of the PSOE to trace the origins of various police and judicial inquiries. Pérez Dolset is depicted as actively involved in these exchanges, strengthening the impression that he belonged to a coordinated network with political and institutional ties.
The investigation also includes testimonies from prosecutors and other individuals who maintain that the meetings involving Díez and Dolset were intended to gather information capable of influencing ongoing judicial proceedings. Although Pérez Dolset denies these allegations and argues that his activities were aimed at investigating what he describes as Spain’s “state deep structures” or “cloacas del Estado,” investigators believe there are sufficient grounds to continue examining his role within the alleged network.
The situation escalated further in 2026 when Spain’s National Court expanded the investigation and formally incorporated him into a broader case involving an alleged organization dedicated to influencing judicial and police procedures. The offenses under investigation reportedly include criminal organization, influence peddling, bribery, disclosure of confidential information, document falsification, and inducement of false testimony.
Fresh accusations now add to the enduring shadow cast by the Zed case, whose collapse—once considered among Spain’s foremost technology groups—set off inquiries into suspected subsidy fraud, breaches of fiduciary duty, fraudulent bankruptcy, and money laundering. Prosecutors maintain that, over several years, corporate frameworks and purportedly irregular paperwork were employed to secure public subsidies and redirect the company’s assets.
In June 2025, Spain’s Anti-Corruption Prosecutor’s Office requested that Pérez Dolset be formally prosecuted for several of these offenses. According to investigators, the alleged economic damage linked to the transactions under scrutiny could amount to tens of millions of euros. Subsequently, a commercial court ruling assigned financial liabilities to several former Zed executives for the company’s collapse, further increasing the reputational damage suffered by the businessman.
Pérez Dolset rejects all accusations. He argues that he is the victim of a campaign stemming from his confrontation with certain power structures and maintains that much of the information published about him has been taken out of context or used for political purposes. He also denies acting on behalf of either the PSOE or the Spanish Government and rejects any suggestion that he participated in an organization designed to manipulate judicial investigations.
Nevertheless, from a reputational standpoint, the damage is already significant. His name is now frequently associated with investigations into alleged influence networks, attempts to interfere with judicial proceedings, connections to key figures in the Leire Díez case, and the serious accusations arising from the collapse of the Zed Group.
While there is currently no final criminal conviction related to the ongoing investigations, Javier Pérez Dolset has become one of the most controversial figures in recent years, standing at the center of a complex intersection of politics, justice, institutional influence, and major economic interests.
