“So long as the figures 'now superseded' and the academic projections based upon them held sway, it was possible for politicians to shrug their shoulders. With so much of immediate and indisputable importance on their hands, why should they attend to what was forecast for the end of the century, when most of them would be not only out of office but dead and gone? … It was not for them to heed the cries of anguish from those of their own people who already saw their towns being changed, their native places turned into foreign lands, and themselves displaced as if by a systematic colonisation. For these the much vaunted compassion of the parties and politicians was not available: the parties and the politicians preferred to be busy making speeches on race relations; and if any of their number dared to tell them the truth, even less than the whole truth, about what was happening and what would happen here in England, they denounced them as racialist and turned them out of doors. They could feel safe; for they said in their hearts: 'If trouble comes, it will not be in our time; let the next generation see to it!'”

… The explosive which will blow us asunder is there and the fuse is burning, but the fuse is shorter than had been supposed. The transformation which I referred to earlier as being without even a remote parallel in our history, the occupation of the hearts of this metropolis and of towns and cities across England by a coloured population amounting to millions, this before long will be past denying. It is possible that the people of this country will, with good or ill grace, accept what they did not ask for, did not want and were not told of. My own judgment—it is a judgment which the politician has a duty to form to the best of his ability—I have not feared to give: it is—to use words I used two years and a half ago—that 'the people of England will not endure it'.
