Billionaire Musk, who has emerged as President Trump's right-hand man, appeared on screen recently at a major AfD rally to endorse the party and tell its supporters that there was "too much focus on past guilt" and that "only the AfD can save Germany".
Two of Europe's far-right parties, France's National Rally and Italian Prime Minister Giorgia Meloni's Mussolini-linked Fratelli d'Italia, insisted on a "clean break" and kicked AfD out of their European Parliament caucus.
Ahead of the German election, Alternative for Germany (AfD) is in second place in opinion polls, at around 22%, behind the CDU/CSU conservatives, on 30%.
The proportional representation (PR) voting system usually means that there is not much change in Germany's political settlement, often after weeks of negotiations with smaller parties until a government with control in the Bundestag can be formed.
One of the party's campaign adverts includes two blonde parents raising their arms to form a symbolic roof over their two blonde children.
