“Why Labour Loses” is an analysis of why Labour has spent long periods in opposition. This book's purpose is to outline the core factors that explain Labour's failures and successes in the last 15 years (2010-2025). There are many competing explanations for why Labour lost four successive elections in the 2010s and how they overturned this losing streak in 2024. Further, there is currently considerable debate around why Labour has lost significant support since their 2024 victory. This allows the book to make a timely and important contribution in answering these questions.

This book argues Labour’s problems stem from members selecting leaders and policies that do not resonate with the public. It also asserts a major shift in the electorate presents Labour with long-term problems, which can explain their drop in support post-2024. It does this by using voters' opinions to understand why voters abandoned and re-joined Labour throughout this period. This data-driven approach provides an impartial and factually correct answer to the controversial question of why Labour spends long periods in opposition. It provides engaging, accessible, and colourful data visualisations to allow a broad audience interested in British politics to gain new knowledge.

This book is a good read for those interested in the Labour Party, polling, electoral trends and British politics. It is also an excellent source for further reading material for any undergraduate British politics course. This book is also recommended for those wanting to understand the impact that party members, Brexit, recessions, leadership and broader social trends have on British politics.
