Kate Middleton has married her prince, she has become a duchess (not a princess - this is Windsor reality rather than a fairytale) and now, like so many new royal entrants before her, she is being "launched" abroad.
The ceremonies will be attended by other invited royals and high-ranking dignitaries, including Britain's Prince Charles and the Duchess of Cornwall, Prince Felipe and Princess Letizia of Spain and Denmark's Crown Prince Frederik and his wife.
