Prince Oscar of Sweden, Duke of Skåne is the younger child and only son of Crown Princess Victoria and her husband, Prince Daniel. He is a grandson of King Carl XVI Gustaf and Queen Silvia and is third in the line of succession to the Swedish throne, after his mother and his sister, Princess Estelle.

Victoria, Crown Princess of Sweden, Duchess of Västergötland is the heir apparent to the Swedish throne, as the eldest child of King Carl XVI Gustaf. If she ascends to the throne as expected, she would be Sweden's fourth queen regnant and the first since 1720. Her inheritance is secured by Sweden's 1979 Act of Succession, the first law in Western Europe to adopt royal absolute primogeniture.
