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.

The fifty-one year old was arrested in 2010 and later admitted 36 charges including attempted rape, inciting a child to engage in sexual activity and voyeurism.
