HC Deb 03 April 1968 vol 762 c97W
Mr. Eyre

asked the President of the Board of Trade, what are his estimates of the annual percentage increase or decrease in demand over the next decade for copper, gold, non-monetary demand only, mercury, nickel, phosphates, silver, tin, tungsten and uranium.

Mr. Darling

The uncertainties are too great for it to be useful to publish estimates of this kind.
