Charlotte gave wheelchair tennis player Shuker a “pinky promise” that she would try the sport alongside her mother.
The Princess of Wales was also introduced to Raducanu, who was knocked out in the fourth round of this year’s championships, telling her: “It was so hard to see you go out.”
US Open winner Raducanu said it was “amazing” to have the support of the princess and “see her here looking so healthy and happy”.
While meeting the players, the Princess of Wales said Charlotte, who was wearing a navy polka dot dress, had been “practising yesterday” and that tennis was “really great for the youngsters”.
The Princess said she had been “filling in the leaderboard” with Charlotte during Wimbledon, adding: “As a family, we play a lot.”
