Royal biographer Lady Colin Campbell has claimed that Prince William and Kate Middleton are “coping as positively as they can” after the Princess was diagnosed with cancer.

In her latest health update announced to the world, Princess Kate revealed she has begun “preventative” treatment after a test found cancer had been present, following her procedure.

During Kate’s video message announcing her cancer diagnosis, she said that her husband was a “great source of comfort and reassurance.”

Kate also said: “We hope that you will understand that, as a family, we now need some time, space and privacy while I complete my treatment.

“My work has always brought me a deep sense of joy, and I look forward to being back when I am able, but for now I must focus on making a full recovery.”

Speaking on GBN America Host Nana Akua said: “The King and Catherine are obviously two of the main star players and the Royal Family.

“Do you remember it in 1992 when the Queen called the year Annus horribilis? It feels like we’re back there again.”

Lady C agreed, responding: “I think to an extent you’re right because so much that’s untoward has gone on.

“Not only in terms of Harry and Meghan and their follower’s antics, but also the health issues.

“William and Catherine are coping as positively and as well as they can. They’re both very levelheaded people, they’re not drama queens like Harry and Meghan, they’re not going to make a drama into a crisis.

A source said that ‘their priority will be to look after each other’

“And they’re going to be coping with this in as measured and sensible a way as possible.

“And I understand from people in the medical profession that she is actually the ideal patient because she’s very positive, she’s very intelligent, she’s not creating a drama and a crisis where there’s no need to.

“And she’s evidently very amenable. She’s very fit, she’s very athletic, so that’s all good.”

The Prince and Princess of Wales are spending the Easter holidays in their country home of Anmer Hall in Norfolk, England.

A source told PEOPLE: “The nuclear family that they have created so well is an immense support not only to him but to Catherine too.”

“It is a particular time in their lives, and I know their priority will be to look after each other.
