In the West German federal election of 1953, Rudel, who had returned to West Germany, was the top candidate for the far-right German Reich Party but was not elected to the Bundestag. Following the Revolución Libertadora in 1955, the uprising that ended the second presidential term of Perón, Rudel moved to Paraguay, where he acted as a foreign representative for several German companies. In 1977, he became a spokesman for the German People's Union, a neo-Nazi political party founded by the extremist politician Gerhard Frey.
