The shock health news follows the King’s diagnosis with cancer, with the condition discovered during his recent hospital treatment.
Here is the timeline of the health troubles facing the royal family.
Monday December 25
In her last public appearance before the news of her hospital treatment, Kate was seen on Christmas Day in Sandringham walking to church with the rest of her family.

Tuesday January 9

She attends the clinic rather than King Edward VII’s Hospital which is usually the go-to establishment for royal medical matters.

Monday January 22
The Queen tells 86-year-old well-wisher Jessie Jackson that the King is “fine”, and thanks her for asking, while she carries out engagements in Swindon.

He told the guests “It means a great deal to us all.”
Monday March 4
The Princess of Wales was photographed for the first time since undergoing abdominal surgery.

Tickets were being sold on the official website for the June 8 military spectacle, advertising an appearance by Kate, on Tuesday evening.
Sunday March 10
Questions were raised that the first picture of the Princess of Wales to be released after her abdominal surgery may have been manipulated before it was posted on social media by Kensington Palace.
The photo of Kate and her children, said by the palace to have been taken by the Prince of Wales in Windsor earlier this week, was posted to mark Mother’s Day.
In the post, she said: “Thank you for your kind wishes and continued support over the last two months.
“Wishing everyone a Happy Mother’s Day. C.”
The picture shows Kate sitting in a chair with her arms around Princess Charlotte and Prince Louis, who are on either side of her, with Prince George standing behind, as all four smile at the camera.
The photograph was shared with media on Sunday but it was withdrawn by international picture agencies later the same day because of concerns that the image had been manipulated.
Monday March 11
The Princess of Wales publicly took the blame for the manipulated family photograph released by Kensington Palace as she issued a personal apology for the “confusion”.
Kate said sorry with a statement on social media which read: “Like many amateur photographers, I do occasionally experiment with editing.
“I wanted to express my apologies for any confusion the family photograph we shared yesterday caused.
“I hope everyone celebrating had a very happy Mother’s Day. C.”
