Buckingham Palace has released the invitation for the upcoming coronation of King Charles III and Queen Camilla, the first time Camilla has been referred to as Queen. The invitation was sent to more than 2,000 guests, including First Lady Jill Biden on behalf of the United States, the first time since 1953 that a U.S. president has not attended the coronation of a British monarch. The invitation marks the first time that Queen Camilla has been referred to as Queen, and the coronation will take place on an as-yet-unspecified date.
