Sat 05 May 2004The Dail uncoveredPolitics: If you have ever wondered what makes politicians do the things they do, or even why they become politicians, then both these books will give you plenty of answers.Let me start with a disclaimer or, as required in political life, a declaration of interest. I feature in Olivia O'Leary's book and I am one of more than a dozen politicians that Katie Hannon interviewed, extensively, for hers. While the two authors have covered similar ground, their approach and the outcome is very different. Both are political journalists and the experience of the day job has obviously informed what they have written.
