The book that has had the biggest impact on me recently is The Revenge of Power, by the former Venezuelan minister Moisés Naím. It crystallised so well a lot of the things that had been keeping me awake at night about the state of our politics, and the state of the world more generally. In particular it focuses on the three Ps that have done so much damage – populism, polarisation and post-truth. You can only begin to address problems as big as those we face if you are clear in your thinking about what those problems are, and where they come from. Read his book and you see the world more clearly. Then it is up to all of us what we do with that. But What Can I Do?: Why Politics Has Gone So Wrong, and How You Can Help Fix It by Alastair Campbell is published by Hutchinson Heinemann. Prue Leith There’s absolutely no doubt in my mind that Henry Dimbleby’s book Ravenous could change the world, or at any rate the UK. It is an analysis of, and solution to, our enormous food problems: food security, sustainability, farming and education. All these areas, all troubled, are very much linked. Dimbleby’s initial report for the government could, and should, have been the start of a revolution that would have had us all buying, cooking, eating, farming and trading differently, with real hope for the future. My hope is that his book will now kickstart the revolution from the bottom up, with the public showing the way to better food education, more sustainable farming, and a generally more enlightened and hopeful food system. And, by the way, it’s an unputdownable, fast-paced, cracking good read. Even if you are not interested in food, three pages in, you will be.
