Ten people went on trial in Paris charged with online harassment of Brigitte Macron over the latest case linked to unsubstantiated gender claims made against the French first lady.

This trial comes after she and President Emmanuel Macron filed a defamation lawsuit in the United States in connection with false claims that Brigitte was born male.

UK correspondent Gavin Grey says Macron's daughter Tiphaine Auziere also testified on her mother's behalf.
