I respect that intervention from the hon. Gentleman, who is the local Member of Parliament for Dounreay. He is entirely right because there is no proven link between leukaemia clusters and nuclear installations. Indeed, leukaemia clusters occur in areas that are far removed from nuclear installations. They also occur in New Zealand, which has no nuclear installations. The subject deserves further study but it is wrong to draw premature conclusions and to scare people unnecessarily before a proven link has been established.

We are committed to the highest safety and environmental standards and put great store by the contractual arrangements in place for the return of wastes.
