Queen Camilla says that King Charles "loves his work and it keeps him going" and that as his health is "getting better… now he wants to do more and more".

Axar.az reports that the King has been receiving cancer treatment for over a year, but this week he completed an intensive schedule of public events on a four-day state visit to Italy.

The Queen's comments were made to the UK press on the trip that also coincided with the royal couple's 20th wedding anniversary.

She said "dream on" to suggestions that the King might take it easier with his workload.

"I think he loves his work, and it keeps him going. And I think it's wonderful, you know, if you've been ill and you are recovering, you're getting better, and now he wants to do more and more and more. That's the problem," said the Queen.

"That's what he's driven by - helping others," she said, while on a tour of Italy.

Royal sources have echoed that the King's treatment has been going well, reflected in how his doctors have let him continue with his work and travels, with more overseas trips expected this year.

"He knows he is fortunate to be in a position to make a difference, and is determined to do just that," said a senior Palace official about the 76-year-old King's determination to keep working.

In terms of getting him to slow down, the official added: "We've all tried! But as people will have seen, the King enjoys his work, he enjoys engaging with as many people as possible."
