TEACHERS and pupils are still at risk of deadly asbestos poisoning, unions warned last night after a court blamed classroom exposure for the death of a retiree.

Lincolnshire coroner Paul Kelly recorded that Elizabeth Belt, who taught in schools in the county from 1968 to 1995, died as a result of an industrial disease.

Ms Belt suffered from mesothelioma, a form of lung cancer which can materialise decades after exposure to asbestos dust, for three years before her death last September.
