Days before the decree absolute of divorce, Letters Patent were issued with general rules to regulate royal titles after divorce. In accordance, as she was no longer married to the Prince of Wales, Diana lost the style Her Royal Highness and instead was styled Diana, Princess of Wales.[fn 2] As the mother of the prince expected to one day ascend the thrones, she was accorded the same precedence she enjoyed during her marriage.Almost a year before, according to Tina Brown, the Duke of Edinburgh had warned the Princess of Wales: "If you don't behave, my girl, we'll take your title away." The Princess of Wales is said to have replied: "My title is a lot older than yours, Philip." She noted that the Spencer family, the family she was born to, is older and more aristocratic than the House of Windsor.Buckingham Palace stated the Princess of Wales was still a member of the Royal Family, as she was the mother of the second and third in line to the throne. This was confirmed by the Deputy Coroner of the Queen's Household, Baroness Butler-Sloss, after a pre-hearing on 8 January 2007: "I am satisfied that at her death, Diana, Princess of Wales continued to be considered as a member of the Royal Household." This appears to have been confirmed in the High Court judicial review matter of Al Fayed &Ors v Butler-Sloss. In that case, three High Court judges accepted submissions that "the very name 'Coroner to the Queen's Household' gave the appearance of partiality in the context of inquests into the deaths of two people, one of whom was a member of the Royal Family and the other was not."Prince William comforted his mother, and he was said to have wanted to let her have the style of Her Royal Highness again. He was reported to have said: "Don't worry, Mummy, I will give it back to you one day when I am King.
