This is the story of modern Britain, focusing on twelve formative days in the history of the United Kingdom over the last five decades. By describing what happened on those days and the subsequent consequences, Andrew Hindmoor paints a suggestive - and to some perhaps provocative - portrait of what we have become and how we got here.
