The Audience is centred on the weekly audiences given by Queen Elizabeth II to Prime Ministers from her accession in 1952 until her death.[2] Three Prime Ministers are omitted from the play: Harold Macmillan, Sir Alec Douglas-Home and Edward Heath are not featured. Tony Blair originally did not feature in the play, but was added when the play transferred to Broadway, replacing James Callaghan, who was excluded from subsequent productions. Advice regarding the political and historical content of the weekly audiences was provided by Professor Vernon Bogdanor (Emeritus Professor of Government at Oxford University), the former tutor of David Cameron, Prime Minister from 2010 until 2016.[3]
