The French prosecutor's office said on Monday that former president Nicolas Sarkozy should be tried in court over accusations that he exceeded the legal limit for spending in his failed 2012 election campaign.
The former French leader, who announced in August that he would run again for the French presidency next year, has long been embroiled in an investigation into alleged overspending on his previous bid.
Sarkozy's lawyer Thierry Herzog accused the prosecutors of "gross political maneuvering."
The 61-year-old lost to current President Francois Hollande in 2012.
The investigators say the prosecutor's office has requested the prosecution of an additional 13 suspects, alongside the former president. A judge will now decide on whether any legal action will be taken.
