Book excerpt: This book examines the political lives and contributions of Margaret Bondfield, Ellen Wilkinson, Barbara Castle, Judith Hart and Shirley Williams, the only five women to achieve Cabinet rank in a Labour Government from the party’s creation until Blair became Prime Minister. Paula Bartley brings together newly discovered archival material and published work to provide a survey of these women, all of whom managed to make a mark out of all proportion to their numbers. Charting their ideas, characters, and formative influences, Bartley provides an account of their rise to power, analysing their contribution to policy making, and assessing their significance and reputation. She shows that these women were not a homogeneous group, but came from diverse family backgrounds, entered politics in their own discrete way, and rose to power at different times. Some were more successful than others, but despite their diversity these women shared one thing in common: they all functioned in a male world.
