I believe a second factor which has weighed heavily in this matter is — Enoch Powell

"The thought struck me for the first time today that our duty to our country may not terminate with the peace – apart, I mean, from the duty of begetting children to bear arms for the King in the next generation. To be more explicit, I see growing on the horizon the greater peril than Germany or Japan ever were; and if the present hostilities do not actually merge into a war with our terrible enemy, America, it will remain for those of us who have the necessary knowledge and insight to do what we can where we can to help Britain be victorious again in her next crisis."

"You have never expressed any decided political opinions, and indeed I do not know if or how far you assent to the proposition that almost unlimited sacrifices of individual life and happiness are worth while to preserve the unique structure of power of which the keystone (the only conceivable and indispensable keystone) is the English Crown. I for my part find it the nearest thing in the world to an absolute (as opposed to a relative) value: it is like the outer circle that bound my universe, so that I cannot conceive anything beyond it."

"It is no accident that the Labour Party of 1964 should share this craving for autarchy, for economic self-sufficiency, with the pre-war Fascist régimes and the present-day Communist states. They are all at heart totalitarian."

"In the end, the Labour party could cease to represent labour. Stranger historic ironies have happened than that."

"It is advertising that enthrones the customer as king. This infuriates the socialist...[it is] the crossing of the boundary between West Berlin and East Berlin. It is Checkpoint Charlie, or rather Checkpoint Douglas, the transition from the world of choice and freedom to the world of drab, standard uniformity."

"The world has recently been treated for nearly a decade to the unusual spectacle of a great empire deliberately taking every possible step to secure its own destruction, because its citizens were so obsessed by prejudice, or incapable of thinking for themselves, as never to perform the few logical steps necessary for proving that they would shortly be involved in a guerre à outrance, which could be neither averted nor escaped."
