"For over ten years, from about 1954 to 1966, Commonwealth immigration was the principal, and at times the only, political issue in my constituency in Wolverhampton. Between those dates entire areas were transformed by the substitution of a wholly or predominantly coloured population for the previous native inhabitants, as completely as other areas were transformed by the bulldozer. My uppermost feeling on looking back upon those years is of astonishment that this event, which altered the appearance and life of a town and had shattering effects on the lives of many families and persons, could take place with virtually no physical manifestations of antipathy. This speaks volumes for the steadiness and tolerance of the natives. Acts of an enemy, bombs from the sky, they could understand; but now, for reasons quite inexplicable, they might be driven from their homes and their property deprived of value by an invasion which the Government apparently approved and their fellow-citizens – elsewhere – viewed with complacency. Those were the years when a ‘For Sale’ notice going up in a street struck terror into all its inhabitants. I know; for I live within the proverbial stone’s throw of streets which ‘went black’."
