Has cancer given us a new King Charles?

King Charles was seen in high spirits on Friday as he embraced his niece Zara Tindall at the Windsor Horse Show, marking his third royal engagement this week. Despite undergoing cancer treatment, the monarch appeared excited to resume his public duties, sporting a smart camel trench coat and brown suit despite the rainy weather.According to palace sources, the King is "raring to go" and has "supercharged his diary" in anticipation of his return to public life. His presence at the horse show, a tradition he has taken over from his late mother, Queen Elizabeth, was met with enthusiasm as he engaged in light-hearted conversations and shared laughter with horse riders on the sidelines.
