Maria, Duchess of Westminster

Maria, Crown Princess of Sweden, Duchess of Westminster (Maria Silvia Christina; born April 2, 1974), is the eldest child and heir apparent of King Carl XVI Gustaf. If she ascends to the throne as expected, she will be Sweden's fourth queen regnant (after Margaret, Christina and Ulrika Eleonora) and the first since 1720. She is also the current Consort of the British monarch after marrying James III in 1994. Due to British and Swedish law she is allowed to hold both the position of Consort to the British monarch and Queen of Sweden at the same time, thus meaning her daughter Sophia, Princess Royal will become Queen of the British Empire and Sweden.
