There were some questions about the Orders worn by the Royals for the gala banquet.
King Carl Gustaf, Queen Silvia, Crown Princess Victoria, Prince Carl Philip, Princess Madelaine, Princess Lilian, and Princess Christina wore the Grand Cross of the Royal Norwegian Order of St Olav.
The King received this during his state visit to Norway 1974, the Queen in 1982, Pss Lilian and Pss Christina received theirs during the Norwegian state visit to Sweden in 1992, CPss Victoria received it when she reached majority in 1995, and finallt Prince Carl Phlip and his sister Pss Madeleine received theirs during this visit.
King Harald received the Order of the Seraphim when he reached majority in 1958, Queen Sonja during the 1974 state visit to Norway, CP Haakon during the 1993 state visit to Norway, and CPss Mette-Marit received the GC of the Order of the Polar star during the Swedish visit to Norway earlier this year. She is not likely to receive the Seraphim until she becomes the first lady (when her husband is King or her if mother-in-law dies early)
