Published alongside a flagship BBC television series to mark her Diamond Jubilee, this book is an account of The Queen's reign. With the flair for narrative and the meticulous research that readers have come to expect, Andrew Marr turns his attention to the monarch - and to the monarchy, chronicling the Queen's pivotal role at the centre of the state, which is largely hidden from the public gaze, and making a strong case for the institution itself. Arranged thematically, rather than chronologically, Marr dissects the Queen's political relationships, crucially those with her Prime Ministers; he examines her role as Head of the Commonwealth, and her deep commitment to that Commonwealth of nations; he looks at the drastic changes in the media since her accession in 1952 and how the monarchy - and the monarch - have had to change and adapt as a result. Indeed he argues that under her watchful eye, the monarchy has been thoroughly modernized and made as fit for purpose in the twenty-first century as it was when she came to the throne and a "new Elizabethan age" was ushered in.
