Horsepower 02

Martin Clunes concludes his worldwide search to discover the secrets of man's partnership with horses. In Italy he watches the colourful Palio horse race, which dates back to the 13th century. Then he rides into battle in a suit of armour at Warwick Castle before witnessing the pomp and ceremony as horses and carriages are prepared for the State Opening of Parliament. On a visit to the USA, he sees how rodeo horses are treated like kings in Las Vegas. Finally, he travels to the remotest parts of central Asia to meet some of the world's greatest horsepeople.
