Have you heard of this guy?
Oswald Mosley was leader of the British Union of Fascists(BUF). …
Mosley was imprisoned in May 1940 and the BUF was banned. He was released in 1943, and, politically disgraced by his association with fascism, he moved abroad in 1951, spending most of the remainder of his life in Paris …
The BUF was protectionist, strongly anti-communist, strongly anti-zionist and nationalistic to the point of advocating authoritarianism. …
I couldn’t recall hearing of any Brits who supported Hitler and Mussolini.
But they did exist.
