asked the Secretary of State for Trade what percentage by volume and by value of the British market in ball and roller bearings is estimated to be supplied by (a) British manufacturers and (b) Japanese manufacturers.

It is estimated that in the 12 months ended September 1980, the share by value of the British market in ball and roller bearings supplied by British manufacturers was 60 per cent.; the corresponding figure for Japanese manufacturers—that is, imports from Japan—was 5 per cent.Information on which to base an estimate of the corresponding shares by volume is not readily available, but it is believed that they are of similar magnitudes.
