King Charles made his first public appearance at Sunday service in Sandringham today since Buckingham Palace announced his cancer diagnosis.

Charles appeared smiling and cheerful with Queen Camilla by his side who was wearing a white coat and black, large hat.

The royal couple were captured on camera walking outside St Mary Magdalene’s church at their Sandringham estate in Norfolk. It was welcomed by the Reverend Paul Williams.

His public “thank you”.

Britain’s King Charles III issued a statement Saturday expressing his gratitude for the messages of support he received after his cancer diagnosis.

“I would like to express my heartfelt thanks for the many messages of support and well-wishes I have received over the past few days,” he says in his first public post since publicizing his health problem.

He also described it as encouraging that going public with his diagnosis helped raise public awareness and promote the work of organizations supporting cancer patients and their families both in the UK and around the world. “The admiration I have always had for their tireless care and devotion is even greater because of my personal experience,” adds the British monarch.
