Staff at Sandal Primary School, Baildon, Bradford, banned all camcorders before the start of the performance to comply with the wishes of a minority of parents.

When angry parents confronted officials they were told the ban was enforced after 20 sets of parents asked on consent forms for images not to be taken at school events.

Mother-of-six Jayne Horsfall, 42, of Baildon, who watched her young child take part in the performance, said she was furious about the ban.

And Shipley Conservative MP Philip Davies said: "I understand when parents with differing views put schools in a difficult situation, and perhaps a no-win situation, but my feeling is that the decision they have made is wrong."

Stephanie Lawrence, chairman of governors, said the school was broadly following advice issued by the Department for Children, Schools and Families.

She said: "Therefore, a letter was sent out to all families at the beginning of the year seeking consent to use photographic images of children.

"Out of the whole school, 20 families requested that the photographs of their children should not be taken. Several of those children recently took part in a short harvest festival. We did not want to remove the children from the performance as we are a very inclusive school."
