PARIS: Former French president Nicolas Sarkozy was placed in custody on Tuesday as part of an investigation into allegations he received millions of euros in illegal campaign financing from the regime of the late Libyan leader Muammar Qaddafi. A judicial source with direct knowledge of the case told The Associated Press that Sarkozy was being held at the Nanterre police station, north-west of Paris. The person spoke on condition of anonymity because he was not authorized to discuss the matter publicly. Sarkozy has vehemently and repeatedly denied wrongdoing in the case, which involves funding for his winning 2007 presidential campaign. Though an investigation has been underway since 2013, the case gained traction some three years later when French-Lebanese businessman Ziad Takieddine told the online investigative site, Mediapart, that he delivered suitcases from Libya containing €5 million ($6.2 million) in cash to Sarkozy and his former chief of staff Claude Gueant. A lawyer for Sarkozy, 63, did not immediately respond to a message from the AP seeking comment. Investigators are examining claims that Qaddafi’s regime secretly gave Sarkozy €50 million overall for the 2007 campaign. Such a sum would be more than double the legal campaign funding limit at the time of €21 million. In addition, the alleged payments would violate French rules against foreign financing and declaring the source of campaign funds. A former top aide of Sarkozy, former minister Brice Hortefeux, was reportedly questioned on Tuesday but was not detained. Sarkozy can be held up to 48 hours and could be placed under formal investigation after his hearing. In the Mediapart interview published in November 2016, Takieddine said he was given €5 million in Tripoli by Qaddafi’s intelligence chief on trips in late 2006 and 2007 and that he gave the money in suitcases full of cash to Sarkozy and Gueant on three occasions. He said the handovers took place in the Interior Ministry, while Sarkozy was interior minister. Takieddine has for years been embroiled in his own problems with French justice, centering mainly on allegations he provided illegal funds to the campaign of conservative politician Edouard Balladur for his 1995 presidential election campaign — via commissions from the sale of French submarines to Pakistan. Takieddine made his accusations at a time when Sarkozy was taking part in the presidential elections’ primary to be the candidate of the right-wing party The Republicans. Sarkozy lost in the first round, ending third behind Francois Fillon and Alain Juppe. Fillon’s own campaign was destroyed by corruption allegations. The former front-runner in the presidential race was charged over the allegations and he suffered a big loss in a vote won by Emmanuel Macron. According to Le Monde newspaper, investigators have recently handed to magistrates a report in which they detailed how cash circulated within Sarkozy’s campaign team. In January, a French businessman suspected of playing a role in the financing scheme, Alexandre Djouhri, was arrested in London on a warrant issued by France “for offenses of fraud and money laundering.” Le Monde said French investigators are also in possession of several documents seized at his home in Switzerland. Sarkozy, who was president from 2007-12, had a complex relationship with Qaddafi. Soon after becoming the French president, Sarkozy invited the Libyan leader to France for a state visit and welcomed him with high honors. But Sarkozy then put France in the forefront of NATO-led airstrikes against Qaddafi’s troops that helped rebel fighters topple his regime in 2011. It is not the first time that Sarkozy faced legal troubles. In February 2017, he was ordered to stand trial after being handed preliminary charges for suspected illegal overspending on his failed 2012 re-election campaign. Sarkozy has appealed the decision.
