Judges Send French Ex-Senator to Jail After He Spiked MP's Champagne

Guerriau drugging conviction

A Paris court on 27 January 2026 convicted former senator Joël Guerriau of drugging National Assembly MP Sandrine Josso in November 2023 and sentenced him to four years in prison, with 18 months to be served behind bars. Prosecutors had sought the same term. The verdict followed Josso’s testimony that she was the only guest at Guerriau’s Paris apartment when he poured her a sweet, sticky glass of champagne, and she called the ruling a 'huge relief'.

The BBC reported that toxicology tests showed Josso had three times the recreational dose of MDMA and that she was taken to hospital after the incident. Spanish outlet El Mundo described the episode as part of a Paris trial that accused Guerriau of drugging Josso in an attempted sexual assault on 14 November 2023 and noted the high-profile nature of the case in France.

Courtroom account of alleged intoxication

Josso’s courtroom account, as reported across outlets, describes an initially convivial visit that later turned alarming. She says Guerriau invited her to celebrate his reelection, created an intimate atmosphere, and served champagne that tasted odd. She experienced tingling, dizziness and other symptoms after drinking.

France 24 records her saying she was the only guest and recalls the sweet, sticky champagne. El Mundo adds that Josso alleges Guerriau performed a suggestive "magic" trick, urged her to finish the drink, and followed her as she fled to a taxi. The BBC corroborates that she left the flat with help from a colleague because she felt unwell.

Guerriau's defence and fallout

Guerriau’s defence, as reported, rejected a sexual motive and described the episode as an accident. France 24 reports he denied sexual motivation, called the incident an accident, said he would appeal, resigned from the Senate, and was expelled from the Horizons party. The BBC quotes Guerriau saying he had been depressed and that he had meant to take the drug himself the previous night but instead 'accidentally' offered a glass containing MDMA to Josso.

He added he was 'disgusted' with his recklessness and denied remembering internet searches about ecstasy and GHB. El Mundo records his political retirement and notes the prior acquaintance between the two, details the defence used to contextualize their relationship during the trial.

National reaction to drugging cases

Journalists place the verdict within wider national concern about chemical submission and other high-profile cases. El Mundo links the trial to a rising problem of chemical submission in France, citing that authorities recorded at least 727 cases in one year. El Mundo also reports that Josso has become a public advocate working with the Mendors pas association.

France 24 likewise notes the case drew national attention amid other high-profile drugging and sexual violence trials in France. The BBC records immediate institutional fallout, reporting that Guerriau was suspended when the charges emerged and underscoring political consequences and public scrutiny.

Conflicting reports and evidence

The coverage shows clear factual conflicts: the court concluded that Guerriau intended to sexually assault and convicted him, while Guerriau says the episode was accidental and denies any sexual motivation. The BBC reports a toxicology finding of three times the recreational dose of MDMA, which contrasts with Guerriau's claim that he had intended to take the drug himself. Each outlet presents statements and evidence rather than accepting the other side's claims as fact; the conviction settles legal responsibility in court, but reporting still reflects contested narratives between the victim's testimony, forensic evidence and the defendant's defence.
