Derb: The Wodehouse character based on Oswald Mosley that your reader is looking for is Sir Roderick Spode. In one speech, Spode proclaims to his brown-shorted cadre, “Nothing stands between us and victory–except defeat!” Spode could hold up well in this year’s Democratic TV debates. Bertie blackmails Spode on Gussie’s behalf in one of the tales (Spode runs a womens’ lingerie line on the side; not what you’d expect from a budding fascist dictator), with the crucial help of Jeeves, of course.
