Carole and Michael Middleton pictured at Wimbledon ahead of Princess Kate’s expected appearance

Carole and Michael Middleton made an appearance at Wimbledon’s eighth day on Monday morning, joining spectators at the All England Lawn Tennis and Croquet Club.

The Princess of Wales’s parents arrived at the London grounds amid overcast conditions, whilst their daughter Kate has yet to attend this year’s tournament.

The 43-year-old Princess, who serves as patron of the tennis club, presented the men’s final trophy to Carlos Alcaraz last year in her second public engagement following her cancer diagnosis announcement.

It is “very likely” that Kate will attend the championships this year, according to reports.

Carole, 70, embraced classic Wimbledon style in a full-length striped dress.

Her outfit was accessorised with a blush-toned structured handbag with short handles and also strappy low-heel sandals

Michael, 76, opted for a smart off-white suit paired with a blue shirt.

The Duchess of Gloucester also joined the pair in the Royal Box, embracing Carole as she took her seat.

Their appearance follows last month’s Royal Ascot, where Carole stepped out in in a yellow lace dress from ME + EM.

Kate had been expected to attend the races alongside her husband but withdrew.

An administrative error the left Ascot officials scrambling to revise the royal carriage list at 12.30pm as the Princess of Wales had been accidentally included just half an hour earlier.

In her absence, Carole was joined by her daughter in law, Alizee Thevenet, who is married to Kate’s brother, James Middleton.

While at the races, Carole also spent time with King Charles and Prince William.

Kate was said to be “disappointed” at missing the famous Berkshire racing event with William and the King and Queen, as she aims to “find the right balance” whilst returning to engagements following cancer treatment.

Royal sources stressed there was “no cause for alarm” and that Kate was adhering to the guidance previously given about finding the right equilibrium in her role.

She has since resumed public duties, visiting Colchester Hospital last week where she spoke about her “really difficult” cancer recovery.

The Princess’s September recovery video highlighted her parents’ crucial support role, featuring footage of Michael and Carole playing cards with the couple and their three children.

The clips suggested the extended family had been instrumental in helping the Wales family through their challenging period.

Royal fans are now eagerly awaiting another appearance from the Kate in her capacity of patron of the All England Lawn Tennis and Croquet Club.

Other royal appearances at this year’s Wimbledon began with Princess Beatrice and Sarah Ferguson, with the Duchess of York ending a 24-year absence from the tennis championships.

On the same day, Lady Gabriella Kingston made a rare appearance in the royal box but do not sit next to the Yorks.

Prince and Princess Michael of Kent have also spectated but did so on separate days.
