French Left-Wing Candidate Challenges Toulouse Election Result Over Suspected Foreign Interference

The defeated left-wing candidate in Toulouse's municipal election has called for the vote to be voided and filed a criminal complaint alleging that foreign digital interference may have influenced the result.

Incumbent mayor Jean-Luc Moudenc, representing the conservative Republicans party, won the election on March 28 with 53.17 percent of the vote, ahead of his France Unbowed rival François Piquemal. Shortly after the result, Piquemal announced on social media that he would pursue legal action to investigate how foreign interference may have affected the vote.

His legal team alleges that fake websites and social media accounts spread disinformation designed to discredit the candidate. They say they were alerted to suspected interference by France's elections coordination and protection network, which includes VIGINUM, the government's foreign digital interference watchdog.

Earlier in March, French newspaper Le Monde reported on a coordinated smear campaign targeting several France Unbowed candidates, including Piquemal. According to the report, fake websites and social media accounts circulated false claims about him, including unfounded allegations of pedophilia posted on Facebook. Most of the content has since been removed. VIGINUM said the campaign's overall reach appeared limited based on low engagement figures but acknowledged that measuring its true impact was difficult.

During the weekend of March 22, as voters headed to the polls for the second round, further incidents were reported. Fake campaign advertisements, purporting to support France Unbowed, appeared across a range of online platforms, including the online marketplace Vinted, the mobile game Candy Crush, sports betting websites, and alongside content from regional newspaper La Dépêche du Midi. These adverts featured the candidate's campaign slogan and logos linked to activist groups but also contained racist messaging.

Piquemal's campaign manager told Euronews' fact-checking team that the campaign became aware of the adverts after people began sending screenshots. She said the adverts appeared to have circulated online for approximately four hours. She expressed certainty that this had an impact on the second round, noting that the content appeared during the legally mandated pre-election silence period, when political campaigning is halted. In that time, she said, thousands of people could have been exposed to defamatory, racist, and Islamophobic posts.

France's elections coordination and protection network says it has identified four separate instances of suspected foreign digital interference linked to the 2026 municipal elections. One technique involves attempts to damage or manipulate political candidates' public image through coordinated online activity.

VIGINUM said it had identified a new informational modus operandi consistent with foreign interference, involving a network of websites and social media accounts displaying technical markers suggesting activity from abroad. An investigation is now underway to identify those responsible. So far, no perpetrators have been publicly named, and it remains unclear whether the alleged campaign had any measurable effect on the outcome of the vote.
