That is correct. In the main, we are dealing here with the interim national agreement. The House will recall that the budget was prepared on the basis of having a pay pause throughout 1976 and, therefore, provision was not made for all the additional remuneration which arose consequent on the implementation of the interim agreement. That sum has to be made up by individual Supplementary Estimates or the Remuneration Vote.
There is also an addition in respect of salaries. Under the costs involved in the introduction of PAYE we estimated it would be necessary to recruit some staff for a short period but in the event, because of additional problems, it was necessary to retain staff for a longer period to do the peak load of work involved in the changeover from one system to another. Some of the staff who were deployed temporarily have since been referred elsewhere and some are still retained. We have, however, been able to effect a saving on the salaries side by the introduction of three computers and the additional sum of £55,000 under travelling and incidental expenses is in a large part attributable to three computers and the accompanying softwear. There has been a saving of nearly £10,000 on travelling so that the main burden of the addition is attributable to the computers, which is a long term economy.
The addition under subhead D in respect of management of Government stocks arises in the main because of the fall in the value of sterling. Some of the expenses in relation to the management of Government stocks are payable in Deutschemarks and other hard currencies such as the US dollar. Under national savings, subhead F, the additional £7,000 is due to the necessity to recoup the Post Office for increases in the salaries of staff on loan to the committee. It is attributable to reasons similar to those I outlined in respect of salaries and is applicable also to Vote 51, Remuneration.
