Billionaire Trump adviser said his ‘significant investments’ in the country justified his wading into German politics

The tech entrepreneur and close adviser to Donald Trump Elon Musk has taken a stunning new public step in his support for the far-right German political party Alternative for Germany (AfD), publishing a supportive guest opinion piece for the country’s Welt am Sonntag newspaper that has prompted the commentary editor to resign in protest.

The commentary piece in German was launched online on Saturday ahead of being published on Sunday in the flagship paper of the Axel Springer media group, which also owns the US politics news site Politico.
