„I have to inform the House that the present situation is so critical that the Government are compelled to seek special powers from the House by a Bill to be passed through all its stages in both Houses of Parliament to-day. The situation is grave.... The Government are convinced that now is the time when we must mobilise to the full the whole resources of this country. We must throw all our weight into the struggle. Every private interest must give way to the urgent needs of the community. We cannot know what the next few weeks or even days may bring forth, but whatever may come we shall meet it as the British people in the past have met dangers and overcome them. But it is necessary that the Government should be given complete control over persons and property, not just some persons of some particular class of the community, but of all persons, rich and poor, employer and workman, man or woman, and all property.“
