It is not possible to make estimates so far ahead as the date which the hon. Gentleman has mentioned. They naturally depend upon the tax rates at the time and their impact on the companies concerned. As the hon. Gentleman will be aware, no royalties start to come until the oil starts to flow.

On the question of education, as I have said there is a very strong case, without going into the question of future royalties, for a centre of this kind to be established in Scotland.
