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 has had to change and adapt as a result. Under her watchful eye, it has been thoroughly modernized but what does the future hold for the House of Windsor?
