Volkswacht Bodensee - First official image published of UK's Princess Kate after surgery

The 42-year-old princess, whose husband Prince William is heir to the British throne, has been recovering mainly at their home in Windsor, west of London, since leaving hospital on January 29.

The photo shows the Princess of Wales sitting on a garden chair, dressed in jeans, a sweater and a dark jacket, smiling, surrounded by her three laughing children, George, Charlotte and Louis.

"Thank you for your kind wishes and continued support over the last two months," read a message accompanying the photo on X.

"Wishing everyone a Happy Mother's Day," said the message, which was signed "C" for Catherine.

In a statement the palace clarified that the photo was taken "in Windsor earlier this week" by Kate's husband, Prince William.

The family photograph is the first official image of Kate released by the royal family since her hospitalisation at the London Clinic on January 16 for an abdominal surgery.

The future queen was last pictured in public during a Christmas Day walk in Sandringham, eastern England.

Photos published by TMZ earlier in March showed Kate wearing sunglasses while being driven in a car, with the celebrity news site saying they were taken Monday near Windsor Castle.

UK media outlets including the Daily Mail and The Sun have chosen not to publish the photos.

The sighting came after a flurry of conspiracy theories on social media over the famously hard-working and dutiful princess's absence from the spotlight.

The speculation came despite Kensington Palace clearly saying at the time of her surgery that she would be "unlikely to return to public duties until after Easter".

It also said the surgery was not related to cancer.

Kate's hospitalisation came almost simultaneously with the announcement that William's father, King Charles, had been admitted for surgery for a benign prostate condition and subsequently diagnosed with an unrelated cancer.

Charles, 75, visited his daughter-in-law's bedside after being admitted himself on January 26.

The king withdrew from public duties during his treatment, though he attended church services and held his weekly audience with the prime minister.

- Camilla steps in -

Charles's wife Queen Camilla, 76, has been the most visible senior royal, stepping in to cover many of her husband's public duties during his treatment.

She is now on a break until March 11, when she is expected to join William and other senior royals at the annual Commonwealth Day service at Westminster Abbey.

She is reported to be on holiday this week, effectively meaning all four of the most senior royals are out of action.

The princess is one of the most popular members of the royal family.

She and William have taken on more royal duties since his younger brother Prince Harry and his wife Meghan left for the United States in 2020, and the king's brother Prince Andrew stepped back because of his friendship with the convicted sex offender Jeffrey Epstein.
