Melbourne: Tennis greats Martina Navratilova and John McEnroe were rapped for breaking "protocols" at the Australian Open on Tuesday after they unfurled a protest banner demanding Margaret Court's name be stripped from a main arena over her controversial views. The two legends had rounded on Court's "homophobic" opinions on Monday, when the 77-year-old Australian was honoured on the 50th anniversary of her 1970 calendar-year Grand Slam. And on Tuesday McEnroe, who had labelled Court a "crazy aunt", and fellow American Navratilova went a step further, according to Australian media.

After a veterans match, they were pictured walking on court with a sign saying, "Evonne Goolagong Arena", calling for Margaret Court Arena to be renamed after three-time Major-winner Evonne Goolagong. According to reports, the 63-year-old Navratilova climbed into the umpire's chair to make a speech, but the television feed was promptly cut. "We embrace diversity, inclusion and the right for people to have a view, as well as their right to voice that view," a Tennis Australia statement said. "But the Australian Open has regulations and protocols with respect to how any fan, player or guest can use our facility, the event and the global stage it provides. This is to ensure the integrity of our event.
