King Charles III has made his first public outing since his cancer diagnosis, attending church alongside Queen Camilla.

The King waved to onlookers as he walked to St Mary Magdalene’s church on the monarch’s Sandringham estate in eastern England on Sunday morning.

Earlier this week he was photographed in the back of a car on his Sandringham Estate.

On Monday, Buckingham Palace announced Charles, 75, had been diagnosed with an undisclosed form of cancer and will step back from public-facing duties while he undergoes treatment.

He was advised by doctors to step away from public-facing duties, but the palace stressed he would continue state duties and paperwork.

Prince William, Charles’ son and the heir to the throne, and Queen Camilla are expected to take on more public engagements to account for Charles’ absence.

Meanwhile, his son Prince Harry made a brief visit to the UK earlier this week after Charles’ diagnosis.

Harry then appeared at the NFL Honors award ceremony in Las Vegas on Thursday, presenting the Man of the Year award.

In his first public comments since his diagnosis, Charles expressed gratitude to the public for their support, saying it brought him “the greatest comfort and encouragement,” according to a statement on Saturday.
