I am sure that the hon. Gentleman has read the Report of the Select Committee of another place, in which Sir Richard Doll, Regius Professor of Medicine at Oxford Univerity, is reported as saying:
In my view the situation is not such as to require any emergency action. I would have thought it was hardly worth the attention of European Ministers at this time when there are a lot of rather more important things to deal with.
That doctor looked into all the implications which are worying the hon. Member and many others and concluded that while, over the course of time, it might be right to phase out lead from petrol and probably everything else, we should not put the country to enormous capital cost at this time when there was no emergency and no basic, fundamental problem.
