Diplômé de l'IEP de Grenoble et du Centre de formation des journalistes (CFJ) de Paris, j'ai démarré ma carrière en 2000 comme journaliste économique, d'abord spécialisé dans les technologies, puis les entreprises. Avant Mediapart, j'ai travaillé pour le magazine Futur(e)s, comme indépendant, à l'agence Reuters, au Journal du Dimanche, puis à Libération, aux services économie puis investigation.
Dans ces médias, j'ai couvert de nombreux secteurs de l'économie française (aéronautique, automobile, santé, industrie, transports...) et enquêté sur des affaires économiques (Airbus, crash du vol Rio Paris d'Air France, Mediator, accident SNCF de Brétigny, fortune belge de Bernard Arnault, affaire Qatar-Veolia...) puis politico-financières (Tapie, Dassault). Je suis le co-auteur du livre Dassault Système (Robert Laffont), avec ma consoeur de France Inter Sara Ghibaudo.
J'ai rejoint Mediapart au services enquêtes en mars 2015. Spécialisé dans les affaires financières, de fraude fiscale et de corruption, je travaille notamment sur les "leaks", ces fuites de données massives qui ont nourri les enquêtes Football Leaks ou Malta Files, publiées par Mediapart avec ses partenaires du réseau European Investigative Collaborations (EIC).
In the interest of transparency towards its readers, Mediapart’s journalists fill out and make public since 2018 a declaration of interests on the model of the one filled out by members of parliament and senior civil servants with the High Authority for Transparency and Public Life (HATVP), a body created in 2014 after Mediapart’s revelations on the Cahuzac affair.
One of the biggest investment funds in European football, Doyen Sports Investments, is controlled by a secretive Kazakh family who made their fortune in a chemicals plant and who hide their vast wealth in the British Virgin Islands. Tevfik Arif, who was for several years a business partner of US president-elect Donald Trump, is the ‘public face’ of the clan of four brothers who run the family’s business activities and who enjoy close links to several oligarchs from the former Soviet Union. In a series of further revelations from documents obtained from the Football Leaks platform by the journalistic consortium European Investigative Collaborations (EIC), Yann Philippin lifts the lid on one of football’s best-kept secrets.
Tevfik Arif is one of the key figures to feature in a series of revelations stemming from documents from the whistle-blowing platform Football Leaks and obtained by the European Investigative Collaborations (EIC) journalistic collective, in which Mediapart is a partner. The Kazakh-Turkish businessman is one of four brothers behind the secretive Doyen Group, and built a property development company in the US largely thanks to his controversial partnership with president-elect Donald Trump, including the construction of the Trump SoHo building in New York. Martine Orange and Yann Philippin report on an association which Trump now claims he has difficulty in remembering.
Serge Dassault, the head of the aviation and defence group that bears his name, a right-wing senator and France's sixth richest person, is accused of laundering the proceeds of tax fraud and of hiding part of his wealth from Parliamentary authorities. The trial, which started on Monday July 4th, focuses on cash hidden in offshore accounts which was allegedly later used to buy votes in the town near Paris where Dassault was mayor. As Yann Philippin reports, the origins of some of these accounts goes back to the days of Serge Dassault's father Marcel, who founded the aviation group.
On Wednesday May 18th Younès Bounouara was jailed for 15 years after being found guilty of trying to kill a man whose secret recording helped expose alleged vote buying by industrialist Serge Dassault in the town where the latter was mayor for many years. The verdict will come as a major embarrassment for Dassault, who has had close ties with Bounouara for more than 20 years. The two men are currently under investigation over the alleged system of vote buying. Yann Philippin reports.
The Panama Papers revelations have rocked the world with disclosures of how Panamanian law firm Mossack Fonseca mounted offshore financial structures for the rich and powerful that enable tax evasion and money laundering on a staggering scale. Beyond the sensational cases emerging in the leaked documents, Mossack Fonseca is also cited in several judicial investigations into some of the most important corruption scandals in France over recent years. Fabrice Arfi, Karl Laske, Mathilde Mathieu, Yann Philippin and Ellen Salvi report.
The attacks in Brussels on Tuesday March 22nd highlight once again how Belgium has become a nerve centre of jihadist terrorism in Europe, as well as being a target itself. The Belgian network led by Abdelhamid Abaaoud, who led the November 13th bombings in Paris, was very active while the logistical 'expert' for the Paris attacks, Salah Abdeslam, who was arrested just last week, is suspected of having been involved in planning the latest attacks in the Belgian capital. Earlier this year, meanwhile, Europol warned of the risk of more attacks. As Belgian authorities identified three men with links to the Paris attacks as the Brussels suicide bombers, Matthieu Suc and Yann Philippin consider how Belgium has become a terrorist hub.
The Paris public prosecutor’s office has opened an investigation into a suspected money laundering operation involving Qatari Sheik Hamad bin Khalifa al-Thani’s French investment arm, French Properties Management (FPM), Mediapart can reveal. The probe, prompted by information from a whistleblowing former employee of FPM, is the latest to target the activities of the Paris-based firm, which is also cited in two other separate judicial investigations in France for “misuse of company assets” and “corruption and influence peddling”. Yann Philippin reports.
French intelligence agencies knew as far back as 2009 that Ismaël Omar Mostefaï, one of the three suicide bombers who attacked the Batalcan concert hall in Paris, had been radicalised in a group in France led by a veteran jihadist with a history of planning terrorist attacks, Mediapart can reveal. Mostefaï had also been spotted with the group when it was under surveillance in April 2014, and the authorities were later informed that he had almost certainly gone to Syria, at the same time as another future Bataclan bomber. But by late 2014 the secret services no longer knew of his whereabouts. He did not resurface again until November 13th, 2015, when he was part of the coordinated attacks that killed 130 people in Paris. The French authorities, however, deny there was any intelligence blunder. Yann Philippin, Marine Turchi and Fabrice Arfi report.
