"The nation has been, and is still being, eroded and hollowed out from within by the implantation of large unassimilated and unassimiliable populations—what Lord Radcliffe once in a memorable phrase called "alien wedges"—in the heartland of the state...The disruption of the homogeneous "we", which forms the essential basis of parliamentary democracy and therefore of our liberties, is now approaching the point at which the political mechanics of a "divided community"...take charge and begin to operate autonomously. Let me illustrate this pathology of a society that is being eaten alive...The two active ingredients are grievance and violence. Where a community is divided, grievance is for practical purposes inexhaustible. When violence is injected—and quite a little will suffice for a start—there begins an escalating competition to discover grievance and to remove it. The materials lie ready to hand in a multiplicity of agencies with a vested interest, more or less benevolent, in the process of discovering grievances and demanding their removal. The spiral is easily maintained in upward movement by the repetitions and escalation of violence. At each stage alienation between the various elements of society is increased, and the constant disappointment that the imagined remedies yield a reverse result leads to growing bitterness and despair. Hand in hand with the exploitation of grievance goes the equally counterproductive process which will no doubt, as usual, be called the "search for a political solution"...Indeed, attention has already been drawn publicly to the potentially critical factor of the so-called immigrant vote in an increasing number of worthwhile constituencies. The result is that the political parties of the indigenous population vie with one another for votes by promising remedy of the grievances which are being uncovered and exploited in the context of actual or threatened violence. Thus the legislature finds itself in effect manipulated by minorities instead of responding to majorities, and is watched by the public at large with a bewildering and frustration, not to say cynicism, of which the experience of legislation hitherto in the field of immigration and race relations afford some pale idea...I need not follow the analysis further in order to demonstrate how parliamentary democracy disintegrates when the national homogeneity of the electorate is broken by a large and sharp alteration in the composition of the population. While the institutions and liberties on which British liberty depends are being progressively surrendered to the European superstate, the forces which will sap and destroy them from within are allowed to accumulate unchecked. And all the time we are invited to direct towards Angola or Siberia the anxious attention that the real danger within our power and our borders imperatively demand."
