King Charles has appointed the Prince William and Princess Kate as grantees of Royal Warrants, marking a significant expansion of their official duties. The new arrangement allows the Prince and Princess of Wales to grant warrants to companies that supply goods or services to their household.

According to the Daily Mail, who dusted off royal author Katie Nicholl's reporting in her book The Making of a Royal Romance, Wills and Kate checked in at a five star resort under the names "Martin and Rosemary Middleton," and then Prince William made Kate a promise.

According to Nicholl, Prince William "assured Kate she was the one," as he wanted to make sure she realized just how serious he was about their renewed relationship. "William, who had inherited something of his father's fear of commitment, knew he would lose Kate if he could not give her some form of guarantee," Nicholl revealed.
