As the right hon. Gentleman is, I am sure, aware, a proposal for a World Health Research Centre has fallen into three main parts—first epidemiological studies, that means the incidence of disease; secondly, a centre for assembling and processing information and, thirdly, by means of establishing a large international laboratory for biological research. On the first two, there is little difference of opinion. On the third, the Advisory Council on Scientific Policy has advised strongly against, but the matter is being considered. The Director-General is making a further study of the matter which will be decided in the light of that study by the countries concerned.
