Catherine, Princess of Wales was told not to be "nervous" at Wimbledon by a young tennis fan

Catherine asked Lydia: "Have you got any advice for me, because I've got a part, I've got to do the prizegiving.

"Any advice for me?"

Lydia replied: "Don't be nervous. Take deep breaths."

The 43-year-old royal responded: "Take deep breaths, OK, I'll remember that. Thank you."

Catherine presented the Venus Rosewater Dish to Swiatek, who thrashed Anisimova 6-0 6-0 in 57 minutes to claim her first Wimbledon title, and was met with a standing ovation when she entered the Royal Box ahead of play starting on Centre Court.

The princess also met young people from the Work at Wimbledon programme and conversed with Shaniah Williams and Jefferson Iweh - representatives from the Wimbledon Foundation.

She also spoke to the tournament's longest-serving steward Bob Flint, who has worked at the All England Club at every Championships since 1980.

Meanwhile, Catherine revealed earlier this month that she had experienced a "really difficult" time following her cancer treatment because she felt as if she was expected to simply "be better" with the disease in remission.

She said on a visit to Colchester Hospital: "There is a whole phase when you finish your treatment, everybody expects you to be better - go! But that's not the case at all.

"You put on a sort of brave face, stoicism through treatment. Treatment's done, then it's like, 'I can crack on, get back to normal', but actually the phase afterwards is really difficult.

"You're not necessarily under the clinical team any longer but you're not able to function normally at home as you perhaps once used to.

"And actually someone to help talk you through that, show you and guide you through that sort of phase that comes after treatment I think is really valuable.

"You have to find your new normal and that takes time."

Catherine said that her cancer diagnosis was "life-changing" for her and her family, husband Prince William and their children Prince George, 12, Princess Charlotte, 10, and Prince Louis, seven.

The princess said: "It's life-changing for anyone, through first diagnosis or post-treatment and things like that.

"It is a life-changing experience both for the individual patient but also for the families as well and actually it sometimes goes unrecognised, you don't necessarily, particularly when it's the first time, you don't appreciate how much impact it is going to have."
