Boris Becker calls for fight against racism amid Twitter spat
Former tennis star Boris Becker said it was time to stand up against racism amid a controversy over a slur directed at his son from the Twitter account of a German nationalist politician.
In an article for Sunday's Welt am Sonntag newspaper, Mr Becker questioned the assertion of Alternative for Germany MP Jens Maier that the tweet about Noah Becker was posted by a member of his staff.
He called for "consequences".
A lawyer for Noah Becker said on Thursday the 23-year-old had filed a criminal complaint against Mr Maier, who has said he regretted the "mishap".
The elder Becker wrote in Sunday's article that racism must no longer be accepted and "it is time to stand up ... here and all over the world".
