Queen Camilla says King Charles is doing 'extremely well' after diagnosis

King Charles "is doing extremely well under the circumstances" following the start of his cancer treatment, Queen Camilla has said.

Asked how the King was doing at an event at Salisbury Cathedral on Thursday evening, she said: "He is very touched by all of the letters and messages the public have been sending from everywhere."

"That's very cheering," she added.

Buckingham Palace announced the King's cancer diagnosis on Monday.
