Carrie Johnson is not only the consort of the Prime Minister, Boris Johnson; she is also considered by some to be the second most powerful unelected woman in Britain after the Queen. Since she moved into Downing Street in July 2019, questions have been raised about her perceived influence, her apparent desire to control events, and the number of her associates who have been appointed to positions of standing in the government machine. So, are these concerns justified? In this carefully researched unauthorised biography, Michael Ashcroft charts the extraordinary ascent of Mrs Johnson, speaking to multiple sources who have been close to her and to Boris Johnson in recent years to produce a fascinating portrait of a woman who is still under the age of thirty-five. The book scrutinises Mrs Johnson's colourful family, her attempt to become a professional actress, and her early decision to work in politics. Long before she moved into No. 10, Mrs Johnson made a name for herself as a Conservative Party press aide before becoming a special adviser to two Cabinet ministers and eventually director of communications at Conservative campaign headquarters. Aside from politics, she is also the mother of two young children and campaigns in the fields of the environment and animal welfare. Carrie Johnson is without doubt a very modern prime ministerial spouse. This examination of her career and life offers the electorate the chance to assess exactly what role she plays in Boris Johnson's unpredictable administration and why that matters.
