A teacher who filmed himself abusing young girls in his classroom at a Weston school was allowed to by 'lamentable failure' by its management.

A Serious Case Review by the North Somerset Safeguarding Children Board has found concerns were raised at Hillside First School 30 times before Nigel Leat's abuse was exposed, though only 11 were formally reported.

The fifty-one year old was jailed indefinitely last year after admitting 36 offences including attempted rape, inciting a child to engage in sexual activity and voyeurism.

Head teacher Chris Wood was later sacked because of doubts about his leadership during the scandal.
