Tennis greats Martina Navratilova and Chris Evert have "turned their backs on women" by opposing plans to stage women's events in Saudi Arabia, the kingdom's ambassador to the United States has claimed.
Last week, the pair wrote an opinion piece outlining their opposition to hosting the WTA Finals in Saudi Arabia.
The WTA is considering moving the season-ending tournament to Riyadh.
Princess Reema bint Bandar al-Saud said their view was "beyond disappointing".
Navratilova, 67, and Evert, 69, each won 18 Grand Slam singles titles between 1974 and 1991.
