Elon Musk on Saturday made a surprise appearance at a rally for Germany's Alternative for Deutschland party, repeating his support for the far-right party as the country's "best hope" as the world's richest person faces accusations of performing a "Sieg Heil" salute at an inauguration event earlier this week.

• Musk, who appeared virtually at the campaign event in Halle, Germany, urged AfD's candidate for chancellor Alice Weidel and her supporters not to lose their national pride: "It's good to be proud of German culture, German values, and not to lose that in some sort of multiculturalism that dilutes everything."
