Judges Renaud Van Ruymbeke and Aude Buresi are investigating Chatillon for alleged "illegal financing" of the Front National.^[1]

French newspaper Le Monde, as part of the Panama Papers investigation reported that Chatillon had used his company to set up an international network of shell companies and false invoices.^[2] On his Facebook page, Chatillon wrote, "obviously, the Front National has nothing to do with this private affair, neither directly or indirectly".^[2] The complex scheme is alleged to involve companies in complex system involving companies in Hong Kong, Singapore, Panama and the British Virgin Islands.^{[citation needed]}

The press allegations have been dismissed by the online news portal Atlantico ^[3] as mere libels and politically oriented news.
