A daughter of France's prime minister became Wednesday the latest to accuse the clergy running a school in the Pyrenees of systemic abuse including while Francois Bayrou was a local official, saying a priest beat her during summer camp when she was 14.

Bayrou's eldest daughter Helen Perlant, who is now 53 and uses her mother's name, said however that her father did not know about the incident.

Multiple accusations of sexual and physical abuse at the Notre-Dame de Betharram boarding school have cast a shadow on Bayrou's premiership.
