When your husband (or wife, in Denis Thatcher's case) becomes Prime Minister, and the doors of No.10 close behind you, every aspect of life is suddenly changed. This was what Cherie Booth discovered. Intrigued, Cherie and social historian Cate Haste set out to explore the experience of previous political generations since the 1950s.

Based on personal interviews, diaries and letters, and the accounts of surviving spouses, families, close friends and colleagues, the story begins with three Conservatives - Clarissa Eden, Dorothy Macmillan and Elizabeth Home. Then comes a shift with the Labour governments and the different backgrounds and attitudes of Mary Wilson and Audrey Callaghan, before the contrasting experiences of Denis Thatcher and Norma Major. Set against the flow of dramatic events on the world stage, this illuminating book explores the pressures of life in the 'goldfish bowl' and offers fascinating insight into the 'political marriage' and the changing role of the leader's spouse.
