Smiling Carole and Michael Middleton step out at day four of Wimbledon

The Princess of Wales‘ mother and father – Carole and Michael Middleton – have attended the fourth day of Wimbledon, in their second public appearance since their daughter’s cancer diagnosis.

Dressed in all their finery, the beaming couple looked in good spirits as they arrived side-by-side for the prestigious event in London.

It follows their cheerful appearance at Royal Ascot last month, when they joined members of the Royal Family, including their son-in-law Prince William, at the lavish occasion.

The Middletons’ outings come after their daughter Kate, 42, who has been receiving chemotherapy for an undisclosed form of cancer since February, made a spectacular return to public life during Trooping the Colour last month. 

Carole, 69, has reportedly been supporting her daughter through her cancer treatment at her home in Windsor.

Michael and Carole’s last public appearance before Royal Ascot was at Kate’s annual Royal Carols: Together at Christmas at Westminster Abbey in London in December. Three months later, Kate announced to the world her cancer diagnosis.

But the royal’s parents have returned to the spotlight recently for the summer social scene after spending months at their daughter’s side. 

They put on a glamorous and joyful appearance at Royal Ascot last month, joining members of the Royal Family at the famous racing event. 

For today’s outing, mother-of-three Carole was the picture of elegance in a floral white, green and pink dress.

Ready for the cooler British weather, she teamed the stunning frock with a white blazer, featuring structured shoulders.

Looking effortlessly chic, the Princess of Wales’ mother accessorized with a pair of sunglasses and tan heels.

Her husband looked equally sophisticated in a smart navy suit, teamed with a blue shirt and a yellow tie.

It isn’t known whether the Princess of Wales, who is the patron of the All England Lawn Tennis and Croquet Club, will attend this year’s tournament. 

However, other recognisable faces have appeared in the Royal Box during the two-week event this year, including the Duchess of Gloucester, former Prime Minister Theresa May, and star athlete Maria Sharapova.

Elsewhere, CEOs and entrepreneurs enjoyed taking in the sport from the coveted seats yesterday.

Wimbledon is set to witness the Battle of the Brits as Katie Boulter and Harriet Dart showdown this afternoon.  

The two British stars will test each other on Court One in front of packed crowds for the women’s game. 

While in the men’s competition Jack Draper and Cameron Norrie will battle it out to get a place in the third round. 

And in what will be an emotional match for Andy Murray, he and his brother Jamie will take to Centre Court for a doubles match – in what the veteran says will be his last Wimbledon. 

This will be the first time the two brothers have have teamed up at a Grand Slam.  Whilst youngster Jacob Fearnley will face off against Serbian Novak Djokovic.
