Britain's King Charles III revealed the emotional toll of his recent cancer diagnosis while meeting with Prime Minister Rishi Sunak at Buckingham Palace on Wednesday.
"Wonderful to see you looking so well," Sunak mentioned to His Majesty, who joked, "It's all done by mirrors."
"We're all behind you, the country is behind you," Sunak insisted.
King Charles III was diagnosed with a form of cancer and is undergoing treatment, Buckingham Palace announced earlier this month. His meeting with the prime minister marked the first time he had publicly discussed his diagnosis.

The Duke of Sussex flew to the U.K. from California to visit his father the following day, and left the country nearly 24 hours later.
On Jan. 17, Charles was scheduled to have a "corrective procedure" for his enlarged prostate. The palace later announced that the surgery had been a success. "His Majesty is doing quite well," a royal source told Fox News Digital.
Earlier in the month, Kate Middleton returned home after a nearly two-week stay in a hospital for a planned abdominal surgery. Kensington Palace shared the news in a statement obtained by Fox News Digital, adding that the Princess of Wales is "making good progress."
On the recommendation of her doctors, the princess will not resume her public duties until Easter, palace officials said.
