Mes sujets de prédilection pendant des années : l'argent des élus et des partis, la corruption, la transparence, les conflits d'intérêts... De 2018 à 2019, je me suis consacrée à des sujets sur les migrations. Puis j’ai intégré la direction éditoriale élargie, de 2019 à 2023, comme responsable du pôle Société. Désormais, je me penche sur les droits des enfants et les violences qui leur sont faites.

Declaration of interest

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.

  • French presidential candidate Fillon on the ropes over wife's payments

    France

    Former French prime minister François Fillon, presidential candidate of the conservative Les Républicains party and widely tipped as the frontrunner in the elections, was this week fighting for his political survival following press revelations that his British-born wife Penelope was paid a total of 500,000 euros out of MPs’ funds to act as his parliamentary assistant, and which cast doubt about whether she actually fulfilled the role. It also emerges that she was paid about 100,000 euros between 2012 and 2013 by a magazine owned by a wealthy Fillon ally. The public prosecutor’s office has now opened an investigation into suspected “misappropriation of public funds” and “misuse of company assets”. Mathilde Mathieu reports on the background to a scandal that not only threatens Fillon’s future, but which could also radically affect the outcome of the presidential elections.  

  • New book reveals François Hollande's disturbing approach to corruption scams

    France — Analysis

    A book published in France this week presents a long series of ‘fireside’ conversations over several years between President François Hollande and two journalists from French daily Le Monde . The book, Un président ne devrait pas dire ça (“A president shouldn’t say that…”), has caused a storm of controversy, notably over Hollande’s attacks on the “cowardly” higher ranks of the French judiciary and which prompted an embarrassed admission of "regret" by the president on Friday over his comments. But, Mediapart investigative journalists Fabrice Arfi and Mathilde Mathieu argue here, the book is especially revelatory of Hollande’s surprising approach to the catalogue of corruption scams which have shaken the French political establishment over recent years.  For he evidently regards them more in terms of their electoral consequences or the negative fallout upon himself than scandals that raise grave concern over the absence of probity in French politics.

  • Sarkozy's former allies openly turn on their old boss

    France — Analysis

    For a long time Nicolas Sarkozy's former allies avoided personal attacks on the former president, even after they had become his political adversaries in the contest to choose the Right's presidential candidate for 2017. Now, however, the gloves are off and some on the Right are openly talking about the string of political and financial scandals in which the ex-president is currently embroiled. For the first time, report Ellen Salvi and Mathilde Mathieu, Sarkozy now looks politically vulnerable to the sheer weight of the scandals and criticism bearing down on him.

  • Revealed: the hidden report on lavish perks paid to former French presidents

    France — Investigation

    A confidential report submitted to President François Hollande two years ago and never made public, authored by the heads of France’s Court of Audit and State Council, estimates the total annual cost of specific perks paid to the country’s three surviving former presidents, plus the provision of personal security protection, at 10.3 million euros, Mediapart can reveal. The 26-page document, published here, recommends that the lavish privileges accorded to them be reduced for reasons of “modernization, transparency and control of public spending”. Mathilde Mathieu reports.

  • Net closes in on Sarkozy law firm partner in tax fraud and money laundering probe

    France — Investigation

    A French judicial investigation has described the “active role” played by Arnaud Claude, the partner of Nicolas Sarkozy in a Paris legal firm, Claude & Sarkozy, in helping an MP and longstanding political ally of the former French president, Patrick Balkany, to conceal from the French tax authorities his ownership of a luxurious Moroccan villa estimated to be worth more than 5 million euros. As the investigation draws to a close, the magistrates in charge have ordered the confiscation of a Normandy property belonging to the lawyer, Mediapart has learned. Fabrice Arfi and Mathilde Mathieu report.

  • Nicolas Sarkozy should stand trial over 'illegal' election funding, say prosecutors

    France

    The French prosecution authorities say the former president should face court proceedings over his role in the “illegal” funding of his failed 2012 presidential election campaign which spent more than double the legal spending limit. It is now for the investigating judges to have the final say as to whether Sarkzoy and others should finally face trial or not. If he is sent for trial it will be a potential blow to the ex-president's political hopes ahead of the 2017 presidential election in which he hopes to be a candidate. But, crucially, any such trial would not be scheduled before next May's election – and if Sarkozy is elected president it would be postponed until 2022 at the earliest. Mathilde Mathieu reports. 

  • Sarkozy walks tightrope to re-election and to escape prosecution

    France

    Nicolas Sarkozy on Monday announced to little surprise that he is standing in the primary elections of his conservative Républicains party this November in the hope of becoming its candidate in next year’s presidential elections. But the former president’s re-election bid is marred by his implication in several judicial investigations, two of which are likely to see him sent for trial. Michel Deléan and Mathilde Mathieu detail the long list of Sarkozy’s judicial woes, and the prospect of his election gamble to avoid prosecution.

  • Audit body slams top French public servant over PR bills and use of luxury hotels

    France

    In 2015 the head of France's National Audiovisual Institute (INA), Agnès Saal, had to quit after piling up thousands of euros in taxi fares in under a year. Now, Mediapart can reveal, the country's spending watchdog, the Cour des Comptes, has pointed the finger at her predecessor Mathieu Gallet over his predilection for expensive hotels and restaurants. Gallet, who ran the INA for seven years before taking over as head of Radio France in 2014, is also criticised over the way the INA awarded lucrative communications and image consultancy contracts during his time in charge. Mathilde Mathieu reports.

  • Sarkozy 2012 campaign spent double the legal cash limit

    France — Investigation

    An expert report has revealed for the first time the full extent of the massive overspend by Nicolas Sarkozy's failed election campaign in 2012. The document, seen by Mediapart, shows that the former president's campaign spent a total of nearly 46 million euros – double the fixed ceiling for a presidential candidate. The overspend includes a 'forgotten' 8.2 million euros whose existence only came to light late in 2015. Mathilde Mathieu reports.

  • Mossack Fonseca's key role in French corruption cases

    International — Investigation

    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 staggering perks paid to France's former presidents and prime ministers

    France — Investigation

    Mediapart has gained access to a detailed account of the annual payments made to former French presidents and prime ministers in a lifelong system of perks and privileges that beggars belief. With items ranging from newspaper and dry-cleaning costs to the payment of staff, offices and vehicles, the country’s three surviving former heads of state cost the taxpayer a yearly 6.2 million euros. Former prime ministers, meanwhile, receive tens of thousands of euros annually for staff and vehicles, including one who left office 25 years ago. Mathilde Mathieu reports.

  • Nice little earner: right-wing French senators get 8,000-euro Christmas 'tip'

    France — Investigation

    It was their secret. Every Christmas from 2003 to 2014, the venerable senators belonging to former French President Nicolas Sarkozy's UMP party, recently renamed Les Républicains, received a hand-out of around 8,000 euros per person on the quiet, on top of their ample salaries and expenses. It was described by the senators themselves as their annual tip or 'Christmas box'. Now the new chairman of their Senate group has decided to put an end to the practice. Mathilde Mathieu reports on yet another example of the Senate gravy-train, which emerges amid a continuing judicial investigation into suspected money laundering and misuse of public funds by the UMP Senate group.

  • Balkany et son ancien bras-droit flashés à Saint-Tropez

    Blog post

    Et de trois. Une fois de plus, Patrick Balkany et son ancien bras-droit, Jean-Pierre Aubry, tous les deux mis en examen pour « blanchiment de fraude fiscale » (entre autres) et soumis à un strict contrôle judiciaire qui leur interdit de se rencontrer, se retrouvent au même moment, au même endroit, sur la même photo. Par hasard, sans aucun doute.

  • Frais des députés : l'appel de Londres

    Blog post

    Pour Pièces à conviction, le journaliste Stéphane Girard a fait le reportage que Mediapart aurait dû réaliser depuis cinq ans. Consacrée aux abus dans les coulisses de l’Assemblée nationale, son enquête, diffusée ce mercredi à 23h10 sur France 3, nous embarque à Londres pour une plongée dans le (contre)-modèle britannique. 

  • Le député Tian et son compte en Suisse : déjà une semaine, ne les oubliez pas

    Blog post

    Voilà déjà une semaine que le député UMP Dominique Tian a reconnu publiquement, contraint et forcé, avoir planqué un compte en Suisse pendant des années. Voilà déjà une semaine que ce pourfendeur patenté de la fraude sociale (celle des autres, celle des « gagne-petit » qui grugent le RSA ou les allocs) a confessé avoir soustrait plus de 1,5 million d’euros au fisc français, avant de profiter d’une circulaire indulgente pour rapatrier discrètement ses billes en 2014. Et rien ne se passe ou presque.

  • Argent du candidat Sarkozy : Mediapart défend la transparence devant le conseil d'Etat

    Blog post

    Mediapart ne lâchera rien. Les citoyens ont le droit de savoir comment le financement des campagnes électorales est contrôlé en France. Avec quelle ardeur, quelle légèreté ou quel aveuglement. Alors que les révélations se multiplient sur les trucages opérés lors de diverses présidentielles, les documents relatifs aux instructions menées par la Commission nationale des comptes de campagne (CNCCFP) sont toujours tenus au secret. En ce vendredi 13 mars, les choses pourraient basculer.

  • A Balkany-city, le monde est petit

    Blog post

    La fortune les abandonne. Hier, Patrick Balkany (mis en examen pour « corruption » et « blanchiment de fraude fiscale ») et son bras-droit Jean-Pierre Aubry (mis en examen pour « complicité de corruption » et « blanchiment de fraude fiscale ») ont manqué de chance : ils ont été repérés discutant devant L’Anjou, un restaurant de Levallois-Perret, alors que le contrôle judiciaire auquel est soumis le second lui interdit de rencontrer le premier –précisément pour éviter qu’ils n’échangent sur l’information judiciaire en cours, menée par les juges Renaud van Ruymbeke et Patricia Simon.
