The family of a man from Mansfield who died of Mesothelioma in 2003 say they are delighted at today’s UK Supreme Court ruling which places insurance liability at the time an employee was exposed to asbestos, not when symptoms appeared.
Leslie Screach was exposed to asbestos fibres between 1963 and 1968 while working as a paint sprayer in west London.
His family started a legal fight for compensation more than five years ago and won the first round of their battle in 2008, when the high court said the firm's insurers at the time workers inhaled fibres were liable.

But two years later the court of appeal said in some cases liability was only triggered when symptoms developed – sometimes decades after exposure.
Today the Supreme court ruled that the disease could be said to have been "sustained" by an employee when they were exposed to the asbestos, even though they became ill afterwards.
