Book excerpt: What is it like to be a wife of a politician in modern-day Britain? Sasha Swire finally lifts the lid. For over two decades she has kept a secret diary detailing the trials and tribulations of being a political plus-one; the travel, the security, the challenges to family life and the unpredictable events. A professional partner as well as a life partner and one with strong political opinions herself, she detonates the image of the dutiful stereotype. Swire gives us a ringside seat through the great political events of the decade, from the election of David Cameron and the forming of a coalition, three general elections, to the referendum and the turmoil of Brexit. She speaks candidly about the key players, at work and in repose. She sheds light on the 'snake and ladder' nature of political careers, on the scandals, on the friendships and the fallouts, the juggling of office and home life, the media scrutiny and the handling of political opponents. It is a searingly honest, wildly indiscreet and often humorous account of what life is like inside the Westminster hot house.
