King Charles attends Easter church service in first major public appearance since cancer diagnosis

King Charles III made his first major public appearance since being diagnosed with cancer, leading the royal family’s Easter church service on Sunday.

The 75-year-old British monarch, who is undergoing treatment for cancer, stepped out at Windsor Castle this weekend with his wife, Queen Camilla, 76.

The couple waved to the crowd outside St George’s Chapel before greeting the church’s clergy ahead of the annual Easter Matins service.

This year, the king is expected to go against tradition by not attending a reception and hosting a private family lunch after the service, on the orders of his doctors.

However, all of Charles’ siblings were present at the service: Prince Andrew and his ex-wife Sarah Ferguson, as well as Princess Anne and Prince Edward.

Noticeably absent were Kate Middleton, Prince William and their three children, Prince George, 10, Princess Charlotte, 8, and Prince Louis, 5, who were not present after the princess’ announcement of his fight against cancer.

The family of five are expected to enjoy a private Easter celebration at their Anmer Hall residence in Norfolk.

It comes a week after Middleton, 42, confirmed her diagnosis and revealed she was undergoing “preventative chemotherapy.”

“I’m doing well and getting stronger every day by focusing on the things that will help me heal, in my mind, body and spirit,” she assured fans, noting that cancer had been discovered after an abdominal operation scheduled for January.

Charles, for his part, announced his cancer diagnosis in February, after undergoing surgery for an enlarged prostate.

He and his daughter-in-law reportedly met for a private lunch to discuss their “shared health experience” before she released a lengthy statement about her diagnosis, sources told People.

The monarch also publicly showed his support, telling Page Six in a statement, via a Buckingham Palace spokesperson, that he was “very proud of Catherine for her courage in speaking out as she did.”

The spokesperson reiterated that Charles had “remained in closest contact with his beloved daughter-in-law over the past few weeks.”
