The Princess of Wales has presented the Wimbledon men’s final trophy to Carlos Alcaraz, in her second public engagement since announcing her cancer diagnosis.

Before passing the trophy to champion Alcaraz, Kate commiserated and shook the hand of runner-up Novak Djokovic.

The princess is a tennis fan and patron of the the All England Lawn Tennis and Croquet Club at Wimbledon.

She arrived smiling at the Wimbledon tennis championships to watch the men’s singles final.

Kate, wearing a purple Safiyaa dress, attended Sunday’s final with her daughter, Princess Charlotte, and her sister Pippa Matthews.

Arriving at Centre Court’s royal box to take her seat, Kate waved to spectators, some holding Union Jack flags, who gave her a standing ovation.

Earlier in the tournament, Kate paid tribute to double champion Sir Andy Murray, saying he should be “so very proud” after he missed out on a final chance at Wimbledon.

In a personally-signed message on social media, the princess wrote: “An incredible #Wimbledon career comes to an end. You should be so very proud @andy_murray. On behalf of all of us, thank you! C.”

The 42-year-old, wife of heir-to-the-throne Prince William, had major abdominal surgery in January that revealed the presence of cancer. She is still having treatment.

Kate returned to public duties in June at the Trooping the Colour, the annual military parade to mark the King’s official birthday, and said she hoped to attend other events over the British summer.

“I am making good progress, but as anyone going through chemotherapy will know, there are good days and bad days,” she said in a personal written message ahead of that appearance.

“My treatment is ongoing and will be for a few more months.”

Her office, Kensington Palace, has declined to give specific details about the type of cancer or her medical condition, other than to say the treatment had begun in February.

The King, 75, has also been treated for cancer.

He returned to public duties in April, and has remained busy, although his daily commitments are limited to minimise risks to his recovery.
