LONDON - More than 500 horses from around the world will take part in an equestrian pageant to mark Queen Elizabeth II's diamond jubilee next year.

Organizers on Tuesday announced details of the spectacle, part of celebrations of the queen's 60 years on the throne.

The "World Comes to Windsor" event will feature 800 performers and 500 horses in a show inspired by the many countries the monarch has visited during her reign -- and her lifelong love of horses.

It will include displays by Britain's Household Cavalry, the Royal Canadian Mounted Police and the New South Wales Mounted Police, as well as by American cowboys, Russian Cossacks and Australian aboriginal performers.

It will be held on May 10, 11 and 13 at Windsor Castle, with the queen attending the final show.
