Serena Williams accused the umpire of being a “thief” in some of the most dramatic scenes at a Grand Slam final after losing to Naomi Osaka.

An Australian cartoonist has defended his depiction of Serena Williams at the US Open, after the image went viral and was criticised as racist and sexist.

@Knightcartoons cartoon is not racist or sexist …. it rightly mocks poor behavior by a tennis legend … Mark has the full support of everyone @theheraldsun pic.twitter.com/KWMT3QahJh — damon johnston (@damonheraldsun) September 11, 2018

Critics, including author JK Rowling, compared the cartoon of Williams to past racist caricatures of African-American people.
