From August 1950 until 1966 Harold Macmillan kept one of the fullest and most entertaining political diaries of the twentieth century. This first volume starts in the last full year of the post war Labour government, follows his rise through the Churchill and Eden governments via a succession of high offices, and culminates with his becoming Prime Minister in 1957. He was an acute observer of events and people not just in his own country or party, but on the wider international and political scene. His Diary provides wry portraits of many of the leading political figures of the period and records his personal take on the great issues and events of the day. In the process Macmillan’s wider activities and inner concerns are also revealed, casting light beyond the famously ‘unflappable’ exterior onto the character of one of the most enigmatic figures in modern British political history.
