Swedish media report that according to the royal court, the funeral of Countess Gunnila Bernadotte af Wisborg, who was an aunt by marriage to King Carl XVI Gustaf of Sweden and Queen Margrethe II of Denmark, will take place in Stockholm on Thursday 29 September, which is the 28th anniversary of hers and the late Count Carl Johan Bernadotte's wedding.
The exact location has not yet been disclosed and the service will be private. The date has been chosen to allow most members of the royal family to attend. Prince Carl Philip and Princess Sofia have consequently postponed their official visit to the Princess's hometown Älvdalen, which was planned for the 29th, until the next day.
There is so far no information about her final resting place, but I suppose the fact that the funeral will take place in Stockholm points to her being buried with Carl Johan Bernadotte in the Royal Burial Ground at Haga rather than with her first husband Carl-Herman Bussler and their two eldest daughters at Bärbo Cemetery in Nyköping. The fact that space has been left open for another name on Carl Johan Bernadotte's tombstone also points to her having chosen Haga.
POSTSCRIPT: The agenda on the royal website now says that the funeral will take place in the Palace Church and will be attended by King Carl Gustaf, Queen Silvia, Crown Princess Victoria, Prince Daniel, Prince Carl Philip and Princess Sofia.
