  • Video rushes expose BFMTV manipulation in Sarkozy-Libya witness tampering case

    France — Investigation

    Mediapart has obtained the rushes, hitherto unseen in public, of a video interview with Ziad Takieddine, a key witness in the probe into the alleged Libyan funding of Nicolas Sarkozy’s 2007 presidential election campaign, in which the Franco-Lebanese business intermediary retracted his earlier testimony detailing how Sarkozy received the cash sums from Tripoli. The video was broadcast as an edited 32-second “exclusive” in November 2020 by French rolling news channel BFMTV, before Takieddine, who had been promised payment, finally disowned his retraction and an investigation into “witness tampering” was launched. The unedited video rushes, published in this report, reveal the extent of the manipulation by BFMTV in operation dubbed “Save Sarko”. Fabrice Arfi, Karl Laske and Antton Rouget report.

  • How French channel BFMTV connived with Sarkozy over Libyan funding case

    France — Investigation

    In November 2020, a key witness in the French judicial investigation into alleged funding by the Gaddafi regime of former president Nicolas Sarkozy’s 2007 election campaign publicly retracted his testimony. French-Lebanese business intermediary Ziad Takieddine had previously detailed how he brought suitcases of cash from Tripoli to Paris for Sarkozy’s campaign. A separate judicial investigation into “witness tampering” subsequently established that Takieddine had been promised several million euros to retract his allegations. Mediapart can now reveal how, illustrated by a remarkable exchange of phone text messages, the management of France’s rolling news channel BFMTV, which broadcast a video of Takieddine’s retraction, connived with the attempt to undermine the Libyan funding probe. Fabrice Arfi, Karl Laske and Antton Rouget report.

  • How Italian 'food nationalism' has blocked Nutri-Score nutrition labelling system in Europe

    International — Investigation

    The food nutrition labelling system known as Nutri-Score was first introduced in France in 2017 and later adopted by Belgium, Switzerland, Germany, Spain, Holland and Luxembourg. The aim of the five-coloured label scheme is to help guide consumers towards eating healthier produce. But on the pretext of defending Italian food, Giorgia Meloni's government and the Italian far right have so far prevented this system from being rolled out across the rest of the European Union. Karl Laske reports.

  • French weekly Le Canard enchaîné seeks minister’s help in sacking one of its investigative journalists

    France — Analysis

    One of France’s oldest existing French press titles, the satirical and investigative weekly Le Canard enchaîné built a reputation as a fearless, irreverent and anti-establishment journal which has recurrently shaken the country’s political class. But it has now turned to the government to validate the disputed dismissal of one of its investigative journalists, following his revelations of a scandal within the weekly itself. Fabrice Arfi, Yunnes Abzouz and Karl Laske report.

  • Why Nicolas Sarkozy faces judicial probe over fake retraction by witness Ziad Takieddine

    France — Investigation

    After a marathon four days of questioning last week, the former president of the Republic was formally placed under investigation for being the “beneficiary of witness tampering” and for “criminal conspiracy”. The investigation in question is into a fake retraction by intermediary Ziad Takieddine, a witness in the scandal concerning alleged Libyan funding of Nicolas Sarkozy's 2007 presidential campaign. Fabrice Arfi, Karl Laske and Antton Rouget report.

  • Jailed fraudster Arnaud Mimran's dreams of vengeance against judges and Mediapart

    France

    French detectives investigating three murders have been eavesdropping on jailed fraudster Arnaud Mimran, one of the brains behind the so-called 'crime of the century' carbon trading scam. As Mediapart has already reported, the listening devices revealed Mimran's prison cell musings about his ties to Israeli prime minister Netanyahu. But they have also revealed the crime boss's plans for revenge, including staging an ambush. One of his targets is Mediapart journalist Fabrice Arfi, the author of a book and numerous articles on the carbon trading affair. Mediapart has now referred the matter to the public prosecutor. Karl Laske reports.

  • Sarkozy's embarrassing book dedication to man who organised key witness's fake retraction

    France — Investigation

    On June 13th and 14th former president Nicolas Sarkozy was questioned by judges as part of an ongoing investigation into the fake retraction by Ziad Takieddine, a key witness in a parallel probe into Libya's alleged funding of the ex-head of state's 2007 election campaign. Under questioning the former president acknowledged that a key figure in the fake retraction case, Noël Dubus, had visited him to receive signed copies of his book. In one copy of his book Nicolas Sarkozy wrote 'Thanks for everything'. Yet businesswoman and paparazzi agency boss Michèle Marchand, who has been placed under formal investigation in the case, had previously denied that this episode even took place. Fabrice Arfi, Karl Laske and Antton Rouget report.

  • Gaddafi funding affair: Sarkozy and three former ministers to stand trial

    France — Investigation

    After ten years of investigation, judges have decided that there is sufficient evidence to send former French president Nicolas Sarkozy to stand trial in the affair concerning the alleged illegal Libyan financing of his 2007 election campaign. The investigating judges are also sending three of the ex-president's ministers for trial in the same affair: Claude Guéant, Brice Hortefeux and Éric Woerth. As Fabrice Arfi and Karl Laske report, this is an unprecedented situation in French political and legal history.

  • The role of a leading farmers' union in France's decision to ban an eco-protest group

    France

    Last week the French government dissolved the environmental protest group Les Soulèvements de la Terre (SLT), which had been prominent in demonstrations against the construction of large irrigation reservoirs in the west of the country. The main farming union, the FNSEA, had been one of the loudest voices calling for this environmental group to be shut down. Now the same powerful farmers' lobby group is pointing the finger at a rival farming union, the Confédération Paysanne, which it says has taken part in SLT protests. Karl Laske looks at the role of the FNSEA and its own history of disruptive actions.

  • Sarkozy-Gaddafi funding affair : the prosecutors' case for sending Sarkozy for trial

    Justice — Investigation

    French prosecutors earlier this month recommended that former French president Nicolas Sarkozy, along with three of his former ministers and nine other individuals, stand trial for the alleged illegal funding of his 2007 election campaign by the regime of former Libyan dictator Muammar Gaddafi. Mediapart obtained access to the 425-page document in which the prosecutors detail the evidence and their conclusions. The Libyan financing arrangements could not have been carried out, they write, “without the consent and the perfect knowledge” of Sarkozy, for whom “the hoped-for advantage consisted of obtaining secret financial support for the 2007 electoral campaign”. Fabrice Arfi and Karl Laske report.

  • 'It was carnage': one young demonstrator's story from France's water protests

    France

    Environment student Lucas, aged 23, took part in the protest on March 25th against against plans to build an irrigation reservoir at Sainte-Soline in west France. It was the first demonstration of this type he had participated in, and he ended up hurling stones at the gendarmes. Here he tells Karl Laske about the reality of being in the middle of brutal clashes which left protestors seriously injured and which sparked controversy over police tactics and the subsequent reaction of interior minister Gérald Darmanin.

  • Evidence and lies: latest revelations as Gaddafi-Sarkozy funding probe awaits outcome

    France — Investigation

    Mediapart can reveal the latest developments that allowed judges to wrap up the Sarkozy-Libyan funding affair probe after nine long years of investigation. Those who are under investigation in the case, including former president Nicolas Sarkozy, now face the possibility of being sent to trial at a criminal court in Paris. Fabrice Arfi and Karl Laske report.
