King Charles III has reportedly left Queen Camilla and other royals concerned about his health as heramped up plans for a royal tour amid his battle with cancer.
The monarch's decision to speed up his royal engagements has rocked the Buckingham Palace as royal aides and well-wishers have asked the King to focus on his health.

The King is said to be determined to push ahead with a tour to Australia, followed by a trip to Samoa for the Commonwealth Heads of Government Meeting, due to take place in mid-October.
