Anne Hidalgo, whose opponents have used the platform to criticise her, citied disinformation and antisemitism as reasons for leaving

The mayor of Paris, Anne Hidalgo, has announced she is quitting X, formerly Twitter, calling it a “gigantic global sewer” that is “destroying our democracies” by spreading abuse and misinformation.

After buying Twitter in 2022, the billionaire Elon Musk laid off thousands of employees, including many who moderated content on the platform. Rebranded as X, it has lost several major advertisers and has been criticised, including by the White House, for not doing enough to curtail antisemitism.

“I have made the decision to leave Twitter,” Hidalgo wrote in lengthy posts in English and French on Monday, citing manipulation, disinformation, antisemitism and attacks on scientists, climatologists, women and liberals.
