It is a pleasure to follow the hon. Member for Jarrow (Mr Hepburn), who spoke with understandable passion. All of us who know something about industrial life in this country are aware that for too long we were literally in a state of ignorance. I think of industrial deafness, which affected members of my family, and of other respiratory diseases. In particular, I think of mesothelioma, and of the date of knowledge in law, which is deemed to
be 1969. It is assumed for the purposes of liability that, until that date, employers, businesses and industries throughout the country—and the people who worked in those businesses, delivering productivity and profit for year after year—were labouring in a state of ignorance. That is a tragedy when we consider the individual stories of the workers and what they went through.
