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.
