King Charles III is showing the world he is a 鈥渟teady hand,鈥 says 麻豆传媒 royal commentator Afua Hagan, after the King attended Sunday services for the first time since his cancer diagnosis was revealed.

鈥淚t was a bit of a surprise because, obviously, he had that diagnosis (announced) on Monday,鈥 Hagan told 麻豆传媒 Channel on Sunday morning. 鈥淲e were told that he was quite tired after his treatment, as anyone would be.鈥

Charles offered spectators a cheerful wave as he walked out of St. Mary Magdalene Church, close to Sandringham House in eastern England.

鈥淨ueen Elizabeth II used to say that she had to be seen to be believed,鈥 Hagan explained, saying that the King stands by the same principle.

鈥淚 think through everything and through it all he still wants people to know that he鈥檚 still here. He鈥檚 still the monarch, he鈥檚 still that steady hand guiding the Royal Family and being head of state.鈥

The specific type of cancer the King was diagnosed with has not yet been revealed.

On Saturday evening, King Charles released a statement, expressing gratitude for messages of 鈥渃omfort and encouragement.鈥

"It is equally heartening to hear how sharing my own diagnosis has helped promote public understanding and shine a light on the work of all those organizations which support cancer patients and their families across the U.K. and wider world," he said in the statement.

"My lifelong admiration for their tireless care and dedication is all the greater as a result of my own personal experience."
