This book gives an overview of each of the British Prime Ministers of the 20th century, summarising their premierships, their policies, and the key events. It is lavishly illustrated with images of documents from The National Archives which give a fresh dimension to the study of the Prime Minister's role, providing insights into their personalities and the pressures that Prime Ministers are subject to. Handwritten comments by Prime Ministers enable the reader to connect with the individual and how they felt at the time. There are dramatic episodes and examples of forthright reactions, but flashes of humour too.
