I love Enoch Powell because of his integrity and the accuracy of his predictions, but he was not the first prominent Brit to warn of the dangers of immigration from the Third World.
Oswald Mosley was warning about such immigration in the 50s...

And Winston Churchill ran on a slogan to “Keep England White” in the mid 50s...

Powell’s point was about culture, not race. He himself despised racism.
So the UK left was utterly wrong to decry him as a racist, whilst the extreme racist right in the UK was and are wrong to see him as a hero.
Sorry, but Mosley was an anti-Semitic, Fascist Nazi-Lover.
