Jean-Marie Le Pen, the 96-year-old founder of the National Front, is at the center of controversy after videos surfaced showing him singing with the neo-Nazi affiliated band Match Retour at his residence.

Despite being deemed unfit for trial due to health reasons, Le Pen is under investigation for embezzlement related to the European Parliament assistants' case.

The videos, released by Mediapart, have sparked outrage, with Marine Le Pen, his daughter, filing a complaint for abuse of weakness against the band.

She argues that her father, though able to recite poetry, is not fully aware of his surroundings.

The incident has raised questions about the influence and presence of extremist groups around the elderly politician.
