The hon. Member for South Ayrshire (Mr. Emrys Hughes) complains that we do not devote enough time to the examination of Supplementary Estimates. It was to make sure that the House, through at least one of its agencies, should devote more examination to Supplementary Estimates that the recent procedure by which they go before the Estimates Committee was introduced. On an earlier Vote I referred to some of the comments which had come from the Estimates Committee on this Supplementary Estimate.
The hon. Gentleman asks about an increase in the provision for civilians at research establishments. I cannot tell him in detail whether this is attributable to increases in pay or increases in numbers, but, in general, under Vote 4, the increased provision this year is attributable to increases in pay. I should be safe in telling the hon. Gentleman that that is the principal reason for the increase to which he has drawn attention.
It is worth saying in regard to this Supplementary Estimate that the original Estimate was for about £500 million. The Supplementary Estimate is for £5 million, representing a rise of 1 per cent. This is due largely to pay and price increases which came upon us since the original Estimate was prepared and which have necessitated the bringing forward of this Supplementary Estimate.
