King Charles thanks medics for his and Kate's cancer care

King Charles thanked the medics who have cared for him and his daughter-in-law Kate, after they both underwent treatment for cancer this year, in a Christmas Day message that touched on global conflicts and the summer's riots in Britain.

In his third Christmas TV broadcast since becoming king, Charles struck an unusually personal tone for the royal seasonal message, a tradition that dates back to a radio speech by George V in 1932.

The year has been traumatic for the royals after Buckingham Palace said in February the 76-year-old had been diagnosed with an unspecified form of cancer detected in tests after a corrective procedure for an enlarged prostate.

A month later, Kate, the wife of his son and heir Prince William, said she was undergoing preventative chemotherapy for cancer that concluded in September. William has said the year has been brutal for the family.

"All of us go through some form of suffering at some stage in our life, be it mental or physical," Charles, who became king in 2022 after the death of Queen Elizabeth, said.

His words were accompanied by footage of a visit he made to a cancer treatment centre on returning to public duties in April and of one of Kate's first engagements when she resumed working.

"From a personal point of view, I offer special heartfelt thanks to the selfless doctors and nurses who this year have supported me and other members of my family through the uncertainties and anxieties of illness, and have helped provide the strength, care and comfort we have needed," Charles said.

"I am deeply grateful too to all those who have offered us their own kind words of sympathy and encouragement," he said in the pre-recorded broadcast that was filmed at an ornate chapel of a former London hospital.

Last week, a palace source said the king's treatment was progressing well and would continue into next year.

Earlier on Wednesday, Charles was joined by his family, including Kate, William and their children, for a traditional church service on his Sandringham estate in eastern England.

Charles' brother Prince Andrew, who was embroiled in another scandal this month when a close business associate was banned from Britain over government suspicions he was a Chinese agent, was a notable absentee from the royal get-together.

DIVERSITY A STRENGTH

The king spoke about nationwide riots, which broke out following the murder in July of three girls at a Taylor Swift-themed event in northern England, and mainly targeted mosques and immigrants.

"Diversity of culture, ethnicity and faith provide strength, not weakness", he said.

"I felt a deep sense of pride here in the United Kingdom when in response to anger and lawlessness in several towns this summer, communities came together not to repeat these behaviours, but to repair, to repair not just buildings, but relationships," he said.

Charles also referenced ongoing wars.

"On this Christmas Day, we cannot help but think of those for whom the devastating effects of conflict in the Middle East, in central Europe, in Africa and elsewhere, pose a daily threat to so many people's lives and livelihoods," he said.
