The princess and Westling announced their engagement last month, sparking huge media interest. Once married, Westling will take the title Prince Daniel, Duke of Västra Götaland.
June 19th has something of a pedigree as a royal wedding day in Sweden. Victoria's mother walked out of the same church as Queen Silvia on 19th June 1976, having tied the knot with King Carl XVI Gustaf.
Earlier monarchs in the Bernadotte dynasty also chose 19th June for their nuptials. On that date in 1823, Crown Prince Oskar - later King Oskar I - married Josefina of Leuchtenberg. Crown Prince Karl, later Karl XV, married Lovisa of the Netherlands on 19th June 1850. In addition, June 19th 1857 saw the arrival in Sweden from Germany of Prince Oskar, later Oskar II, following his marriage there to Sofia of Nassau.
The palace's statement did not reveal who will conduct Victoria and Daniel's ceremony, but the Church of Sweden's Archbishop traditionally takes the role.
The statement said that planning for the big day was continuing under the supervision of Major General Håkan Pettersson, head of the King's military staff and official wedding coordinator.
