Two French women who falsely claimed that the country's First Lady, Brigitte Macron, was transgender have been found guilty of slander.
In December 2021, Natacha Rey and Amandine Roy broadcast unsubstantiated rumours online that Brigitte had never existed, and that her brother Jean-Michel Trogneux had changed gender and started using that name.
The defendants were ordered to pay €8,000 (£6,750; $8,859) in damages to Mrs Macron, and €5,000 to her brother.
The French courts recognising and acknowledging that Brigitte Macron and her brother are of course two separate people, to the point where compensation for slandering was paid out separately to each of them.
This demolishes the foundations of this silly conspiracy theory.
