No Kate, No Crown: 'Without' the Princess of Wales' Star Power the Royal Family 'Is Finished'

Catherine, Princess of Wales' "shocking" cancer diagnosis has thrown an "even bigger" spotlight on King Charles III's slimmed-down monarchy.

"I want them to pull through this crisis," Princess Diana's former butler, Paul Burrell, told an outlet when speaking about William and Catherine's recent press struggles. "I want them to show the world that everything is well within the house of Wales, and I want them to go forward because they are our hope for the future. Without them — without Kate — the royal family is finished."

The Princess of Wales revealed her diagnosis in a candid and "heartbreaking" video where she sat on a bench in front of a garden.

"I wanted to take this opportunity to say thank you, personally, for all the wonderful messages of support and for your understanding whilst I have been recovering from surgery," the princess shared. "It has been an incredibly tough couple of months for our entire family, but I’ve had a fantastic medical team who have taken great care of me, for which I am so grateful."

At the end of the message, the future queen movingly reminded "all those suffering with this disease" to "never lose hope" and reminded them that "they are not alone."

King Charles III, who is also receiving treatment for an unknown cancer, shared that he is "so proud of Catherine for her courage in speaking as she did."

Another family source also revealed: "The day the family found out was the day William canceled going to the memorial of his godfather, King Constantine of Greece," they added. "They have been processing the information and Kate has already started chemotherapy."

The disease is said to be "in its earliest stages," which is also where Kate's treatment currently is. "My medical team therefore advised that I should undergo a course of preventative chemotherapy, and I’m now in the early stages of that treatment," HRH explained. "This, of course, came as a huge shock, and William and I have been doing everything we can to process and manage this privately for the sake of our young family."

"As you can imagine, this has taken time," the queen-in-waiting continued. "It has taken me time to recover from major surgery in order to start my treatment. But, most importantly, it has taken us time to explain everything to George, Charlotte and Louis in a way that is appropriate for them, and to reassure them that I am going to be ok."

"As I have said to them; I am well and getting stronger every day by focusing on the things that will help me heal; in my mind, body and spirits," the senior royal added.
