I can assure the hon. Gentleman that that particular work, which was commissioned a while ago, will complete its normal course in two years when full assessment will have been completed to a depth of 600 ft. If my memory serves me right, arguments to go down to 6,000 ft—which is what we are talking about in the north-west frontier acreage—is totally unreasonable and unnecessary. Of course, we shall review carefully arrangements with outstanding organisations such as the one that the hon. Gentleman mentioned. However, I emphasise that we are not curtailing a report. It will come to its full and complete conclusion in two years.
