Mr. Robert Watt:

In such a case it is very difficult to anticipate the amount of work involved and the amount of activity, but we would give a view on whether the cost estimate is robust and reasonable. It is the parent Department's responsibility to state what it believes is the likely work and the likely cost and we give a view on this. As the Chairman knows, there is much uncertainty about what inquiries and investigations are likely to discover and their level of activity, so there is more uncertainty about budget estimation than in other areas of activity. We can certainly come back to the Chairman on what was the original estimate.
