THE First Minister has urged for the "privacy" of the Princess of Wales to "be respected" following her announcement that she is being treated for cancer.

Kate revealed she is undergoing treatment for cancer in a video message and told others battling the disease “you are not alone”.

She spoke about the “huge shock” of the medical development and how her family have experienced an “incredibly tough couple of months”.

In reaction to the video announcement, Yousaf said: "I'm deeply saddened to hear the news about the Princess of Wales/Duchess of Rothesay. I am praying for her swift recovery.  

"It must be an incredibly difficult time for the whole family. Royalty or otherwise, she has a right to privacy, which I hope will be respected."

The princess was admitted to hospital for abdominal surgery on January 16 and at the time her condition was thought to be non-cancerous, but tests after the successful operation found cancer, the type of which has not been disclosed.

The future Queen began a course of “preventative chemotherapy” late in February but is said to have a positive mindset for her recovery and is in good spirits, describing herself as “well and getting stronger every day”.

SNP Westminster leader Stephen Flynn said he had “no doubt” that the Princess of Wales’s words will be “of comfort and support to others” facing a battle against cancer.

The MP said in a post on Twitter/X: “We all know the suffering and distress that a cancer diagnosis brings to individuals, their families and friends.

“I wish Kate well in her battle, and have no doubt that her words will be of comfort and support to others facing their own.”
