King Charles III of Britain is expected to attend an Easter service today, Sunday, at St. George's Chapel in Windsor. This public appearance is considered the most significant for the king and marks a major royal engagement since his cancer diagnosis. The king's participation in the Easter service is seen as a move to reassure the public following the shocking news. A senior source from within the royal family informed "In Touch" that King Charles is not only battling pancreatic cancer but also has only two years left to live. Although he will attend the Easter service in Windsor, the king is absent from the royal calendar in the foreseeable future and is heavily relying on his sister, Princess Anne, to carry out royal duties.
