Princess Anne Marie of Denmark will soon become the youngest queen in the world, although at age 17, she is too young to marry under Danish law, reports United Press.
When Princess Anne Marie, youngest daughter of King Frederik IX, marries King Constantine II of Greece, 23, they will become "the youngest couple to share a European throne this century."
The wedding is expected to take place after the official mourning period for Constantine's father, King Paul, ends on June 6. If the wedding takes place before Anne-Marie's 18th birthday on August 30, she will have to ask for a 'King's letter,' giving "Danish girls under 18 special permission to marry."
Princess Anne-Marie and King Constantine II share common descent from King Christian IX of Denmark and Britain's Queen Victoria.
