 The book, excerpts from which were published in the "Daily Mail" prior to publication, received significant media attention, particularly relating to allegations made about Cameron.
 It is published by Biteback, a company in which Ashcroft has a majority share, run by political blogger Iain Dale.
The Conservative Party, officially the Conservative and Unionist Party, is a centre-right political party in the United Kingdom.
 It is currently the governing party, having been so since the 2010 general election, where a coalition government with the Liberal Democrats was formed.
 In 2015, the Conservatives led by David Cameron won a surprise majority and formed the first Conservative majority government since 1992.
 However, the 2017 snap election on Thursday 8 June resulted in a hung parliament, and the Conservatives lost their parliamentary majority.
 They are reliant on the support of a Northern Irish political party, the Democratic Unionist Party (DUP), in order to command a majority in the House of Commons through a confidence-and-supply deal.
 The party leader, Theresa May, has served as both Leader of the Conservative Party and Prime Minister since 13 July 2016.
 It is the largest party in local government with 9,237 councillors.
 The Conservative Party is one of the two major contemporary political parties in the United Kingdom, the other being its modern rival, the Labour Party.
 The Conservative Party's platform involves support for free market capitalism, free enterprise, fiscal conservatism, a strong national defence, deregulation, and restrictions on trade unions.
The premiership of David Cameron began on 11 May 2010 when Cameron accepted the Queen's invitation to form a government.
 This occurred upon the resignation of Cameron's predecessor as Prime Minister of the United Kingdom, Gordon Brown.
 While serving as Prime Minister, Cameron also served as First Lord of the Treasury, Minister for the Civil Service and Leader of the Conservative Party.
The Afghan hijackers case refers to a series of United Kingdom judicial rulings in 2006 in which it was ruled a group of nine Afghan men, who had hijacked an aircraft to escape the Taliban, had the right to remain in the UK.
 The case provoked widespread political controversy and was questioned by large sections of the media, causing widespread condemnation by many newspapers (most notably "The Sun"), and the leaders of both the Labour Party and the Conservative Party.
 Prime Minister of the United Kingdom Tony Blair called the ruling "an abuse of common sense", while the Conservative Party leader David Cameron pledged to reform British human rights legislation to prevent a recurrence of such situations.
"Piggate" refers to an uncorroborated anecdote that during his university years former British Prime Minister David Cameron put a "private part of his anatomy" into a dead pig's mouth as part of an initiation ceremony for the Piers Gaveston Society.
 The anecdote was reported by Michael Ashcroft and Isabel Oakeshott in their unauthorised biography of Cameron, "Call Me Dave", attributing the story to an anonymous Member of Parliament who was a "distinguished Oxford contemporary" of Cameron's.
 Extracts from the book were published in the "Daily Mail" on 21 September 2015, prior to its publication.
