David William Donald Cameron (; born 9 October 1966) is a British politician who was Prime Minister of the United Kingdom from 2010 to 2016 and Leader of the Conservative Party from 2005 to 2016. He was Member of Parliament (MP) for Witney from 2001 to 2016. Cameron identifies as a One-Nation Conservative, and has been associated with both economically liberal and socially liberal policies. Born in London to wealthy upper middle-class parents, Cameron was educated at Heatherdown School, Eton College, and Brasenose College, Oxford.

The Conservatives' unexpected success in the 1992 election led Cameron to hit back at older party members who had criticised him and his colleagues, saying "whatever people say about us, we got the campaign right," and that they had listened to their campaign workers on the ground rather than the newspapers. He revealed he had led other members of the team across Smith Square to jeer at Transport House, the former Labour headquarters. Cameron was rewarded with a promotion to Special Adviser to the Chancellor of the Exchequer, Norman Lamont. Cameron was working for Lamont at the time of Black Wednesday, when pressure from currency speculators forced the pound sterling out of the European Exchange Rate Mechanism. At the 1992 Conservative Party conference, Cameron had difficulty trying to arrange to brief the speakers in the economic debate, having to resort to putting messages on the internal television system imploring the mover of the motion, Patricia Morris, to contact him. Later that month Cameron joined a delegation of Special Advisers who visited Germany to build better relations with the Christian Democratic Union; he was reported to be "still smarting" over the Bundesbank's contribution to the economic crisis. Lamont fell out with John Major after Black Wednesday and became highly unpopular with the public. Taxes needed to be raised in the 1993 Budget, and Cameron fed the options Lamont was considering through to Conservative Campaign Headquarters for their political acceptability to be assessed. By May 1993, the Conservatives' average poll rating dropped below 30%, where they would remain until the 1997 general election. Major and Lamont's personal ratings also declined dramatically. However, Lamont's unpopularity did not necessarily affect Cameron: he was considered as a potential "kamikaze" candidate for the Newbury by-election, which includes the area where he grew up. However, Cameron decided not to stand. During the by-election, Lamont gave the response "Je ne regrette rien" to a question about whether he most regretted claiming to see "the green shoots of recovery" or admitting to "singing in his bath" with happiness at leaving the European Exchange Rate Mechanism. Cameron was identified by one journalist as having inspired this gaffe; it was speculated that the heavy Conservative defeat in Newbury may have cost Cameron his chance of becoming Chancellor himself, even though as he was not a Member of Parliament he could not have been. Lamont was sacked at the end of May 1993, and decided not to write the usual letter of resignation; Cameron was given the responsibility to issue to the press a statement of self-justification.Answer this question using a quote from the following article:
