On the day Empire Windrush arrived in Britain in June 1948, 11 Labour MPs sent a letter to the prime minister, Clement Attlee, proposing that there should be controls on black immigration.
The British people were “blest by the absence of a colour racial problem”, they wrote, adding: “An influx of coloured people domiciled here is likely to impair the harmony, strength and cohesion of our people and social life and cause discord and unhappiness among all concerned.”
