The right hon. Gentleman will know that there are a large number of factories in Acton. He said that he wishes to save 20 per cent. of industrial and commercial use of electricity. Will he explain why he has not asked every unit of production to economise by 20 per cent., or more, and show that it has done so, rather than adopt the three-day solution which will have considerable industrial and social secondary effects and, from what I have heard in my Constituency, will cause a reduction in production which would not otherwise take place?
