Title issues: Sofia Hellqvist to become a princess and a duchess

With less than a month to go before the wedding of Prince Carl Philip of Sweden and Sofia Hellqvist on 13 June, the banns of marriage were published in connection with a service in the Palace Church in Stockholm on Sunday. This is no longer mandatory, but the Swedish royal family upholds the tradition and uses it as an occasion for the presentation of wedding gifts.
King Carl Gustaf also took the opportunity to announce his decision that Sofia Hellqvist will receive the titles Princess of Sweden and Duchess of Wermlandia as well as the style Royal Highness. This is not automatic, but decisions about titles for members of the royal family are the King's prerogative. As a logical consequence of the introducing of gender-neutral succession, King Carl Gustaf decided to treat the issue of princesses in the same way as the issue of princes, which means bestowing royal titles upon the children of Princess Madeleine. However, he seems to have changed his mind when it comes to the titles of his younger children's spouses.
When Princess Madeleine became engaged to Jonas Bergström in 2009, it was announced that her future husband would become Duke of Helsingia and Gastricia, i.e. of his wife's dukedom, but not a prince. On the other hand, her marriage to Christopher O'Neill in 2013 was preceeded by an announcement that her husband would become neither a prince nor a duke since he would not become a Swedish citizen and was not willing to give up his business interests, which suggests that the title of prince had been offered in addition to that of duke, as is now the case with the future wife of Prince Carl Philip.
The service in the Palace Church, which was followed by a lunch and reception, was attended by among others King Carl XVI Gustaf and Queen Silvia, Crown Princess Victoria and Prince Daniel with Princess Estelle, Princess Madeleine and Chris O'Neill with Princess Leonore, Princess Christina's son Gustaf Magnuson and his wife Vicky Andrén, the King's aunt by marriage Countess Marianne Bernadotte af Wisborg, and Sofia Hellqvist's parents Erik and Marie Hellqvist as well as her sisters Lina and Sara with their boyfriends Jonas Frejd and Oskar Bergman.
