Banning Muslim girls from wearing headscarves in class would be a serious setback in the fight against racism, teachers have been warned.
Hundreds of teachers from England and Wales are attending a conference in Harrogate. Several speakers urged them to support the wearing of headscarves.
"Children have to be prepared for life in a multi-cultural society," said one.
It comes after the French government voted to ban headscarves and other religious items from the classroom.
