King Charles III

Kate Middleton attended the Trooping the Color parade Saturday in honor of King Charles III’s birthday. It was her first public appearance since her cancer diagnosis earlier this year.

Kate, the Princess of Wales, shared an emotional letter after missing the rehearsal.

Kate Middleton will miss the Trooping the Colour public rehearsal, but will she make a surprise balcony appearance?

Top moments that stood out on social media included a red feather, a kiss, and, of course, the facial expressions of little Prince Louis.

King Charles III has been crowned at Westminster Abbey, the final mile of a seven-decade journey from heir to monarch.

UK Republicans argue that the monarchy is outdated and undemocratic, and that the country should be a republic with an elected head of state. The call for a republic has gained momentum in recent years.

"The resemblance is uncanny."

Defense Secretary Ben Wallace said it would be “a spectacular and fitting tribute" to the monarch, who is also commander-in-chief of the U.K. armed forces.

The coronation of King Charles III is expected to be a shorter, less extravagant ceremony than the three-hour service that installed Elizabeth II 70 years ago. Here are the plans.

The palace says that rather than commission a new crown, as is customary, Camilla will modify Queen Mary’s crown using diamonds from Queen Elizabeth II’s personal collection.

"Christmas is a particularly poignant time for all of us who have lost loved ones," Charles said. "We feel their absence ... and remember them in each cherished tradition."

Rishi Sunak met at Buckingham Palace on Tuesday with the king, who had just accepted the resignation of Liz Truss. Sunak is the third Conservative prime minister this year.

King Charles III will be crowned at Westminster Abbey on May 6 in a ceremony that will embrace the past but look to the modern world after the 70-year reign of the late Queen Elizabeth II.

A surging tide of people — ranging from London retirees to former England soccer captain David Beckham — have lined up to file past Queen Elizabeth II's coffin as it lies in state at Parliament, so many that authorities had to call a temporary halt Friday.

Resurfaced photos of King Charles' swollen fingers have led some on the internet to either poke fun or express serious concern.
