Something Understood - The Best Words

Mark Tully talks to poet and novelist Louis de Bernieres about the difference between poetry and prose. Is poetry, as Coleridge has said, "the best words in the best order"? Is it true that poetry is really better than prose at expressing emotion? And can poetry really change the world, as at least one writer believes?
