After a riot in Bristol in 1980, Powell asserted that the media were ignoring similar events in south London and Birmingham, and claimed: "Far less than the foreseeable New Commonwealth and Pakistan ethnic proportion would be sufficient to constitute a dominant political force in the United Kingdom able to extract from a government and the main parties terms calculated to render its influence still more impregnable. Far less than this proportion would provide the bases and citadels for urban terrorism, which would in turn reinforce the overt political leverage of simple numbers". He attacked "the false nostrums and promises of those who apparently monopolise the channels of communication. Who then is likely to listen, let alone to respond, to the proof that nothing short of major movements of population can shift the lines along which we are being carried towards disaster?"
