The Diamond Queen is a BBC documentary series, presented by Andrew Marr, which looks at the life of Queen Elizabeth II. The series focuses on her accession, her daily routine, how she is seen as a role model, and how she coped in her 60th year as monarch. The programme features archive footage of the Queen, as well as in-depth footage of her major engagements since the beginning of 2010 to late 2011. In the final episode, the defining moments of the Queen's reign are covered, starting with her accession to the throne in 1952 until her coronation sixteen months later. Marr follows her trip to Australia to look at what he opines is her most enduring achievement, the Commonwealth, looks back upon her Silver and Golden Jubilees in 1977 and 2002 respectively, and comments on how she has coped with changing and occasionally tense relations with the media. Also touched upon is how she coped with the deaths of her mother and sister within weeks of each other in the run up to her Golden Jubilee, and the entire range of her adult grandchildren have their say about the Queen.
