Elon Musk made a surprise appearance at a far-right campaign event in Germany where he urged supporters to move beyond their “past guilt”. Speaking via video link to a hall of around 4,500 Alternative for Germany (AfD) supporters in the central city of Halle, the world’s richest man said: “It’s good to be proud of German culture, German values, and not to lose that in some sort of multiculturalism that dilutes everything.” Mr Musk caused outrage last week after making a gesture at Donald Trump’s inauguration which many compared to a Nazi salute.
