Former French president Nicolas Sarkozy went on trial on Thursday over claims of illicit financing for his failed 2012 re-election campaign, months after he was convicted in a landmark corruption case.
Mr Sarkozy, 66, became France's first post-war president to be sentenced to prison when judges gave him a three-year term in March for corruption and influence peddling, although under sentencing rules he is not likely to spend any time behind bars.
He and 13 others are accused of setting up or benefiting from a fake billing scheme to cover millions of euros in excess spending on campaign rallies to fend off his rival and successor Francois Hollande.
Prosecutors say accountants warned Mr Sarkozy the campaign was set to blow past the €22.5 million ($27m) spending cap, but he insisted on holding more events.
Eventually, the campaign spent nearly €43m, although Mr Sarkozy said he was unaware of the scheme.
Unlike some of the defendants, he is not charged with fraud, but with the lesser offence of illegal campaign financing.
If convicted, he risks up to a year in prison and a fine of €3,750.
Mr Sarkozy did not appear in court when the trial opened, but he has been ordered to appear for questioning in the week beginning June 14.
The trial was originally set for March but was postponed after a lawyer for a key witness was hospitalised with Covid-19. It is now set to run until June 22.
The case is one of several to have dogged Mr Sarkozy since he left office and which have torpedoed hopes among his allies that he could muster a comeback and challenge Emmanuel Macron next year.
He has denied any wrongdoing, saying he is the victim of a vindictive judicial system that widely opposed his reform efforts while in power from 2007 to 2012.
He has appealed the corruption conviction, handed down after a judge ruled he plotted with his former lawyer and friend Thierry Herzog to obtain and share confidential information from a judge about an inquiry into his 2007 campaign financing.
The latest case is known as the Bygmalion affair, after the name of the public relations firm hired to orchestrate a blitz of elaborately staged rallies when polls showed that Mr Sarkozy's 2012 re-election was far from assured.
Bygmalion executives have acknowledged a system of fake invoices to pass the bills to Mr Sarkozy's UMP party, since renamed Les Republicains, including the deputy manager of the campaign, Jerome Lavrilleux.
Mr Lavrilleux made headlines in 2014 after he tearfully confessed to the scam during a French TV interview, saying: "This campaign was a runaway train that no one had the courage to stop."
Campaign officials refused to reimburse the spending after investigators discovered the fraud, prompting the UMP to launch a "Sarkothon" that raised €11 million towards his costs.
Mr Sarkozy, who married singer and former model Carla Bruni while in office, is also facing charges he received millions of euros from the former Libyan dictator Muammar Qaddafi for his 2007 election campaign.
And in January, prosecutors opened an investigation into alleged influence-peddling during his activities as a consultant in Russia.
Yet, Mr Sarkozy remains a popular figure on the right, attracting long lines of fans last summer seeking autographs of his latest memoir, The Time of Storms, which topped bestseller lists for weeks.
