The hon. Gentleman has left the question of the figures, but I should just like to put this matter right. So far as I can see—and I have taken a great deal of trouble in working out the calculations—it is impossible to tell what speculative offices have been built. There is no record. Therefore, I am telling the hon. Gentleman that he has no right to make such a statement. So far as the percentage is concerned, the Parliamentary Secretary made a great slip of the tongue when he said that 10 per cent. of the total building labour force in Britain was employed in the London region. The figures of the hon. Member for Willesden, East (Mr. Freeson) are even worse.
