After its disastrous defeat in 2015, Labour is at grave risk of throwing away the 2020 general election. The party has to understand why it suffered such a devastating defeat and learn crucial lessons if it is to recover. The reasons appear obvious enough: the British public did not believe that Ed Miliband was a credible prime minister; people feared that a Labour government would plunge the British economy back into chaos; and they perceived that the party was out of touch on issues like immigration and welfare. Labour was not just narrowly defeated in 2015, it was overwhelmingly rejected by an electorate who no longer trust the party.

Underlying all of this is a sense that Labour is a party that does not understand the modern world, wedded to an outdated 'cloth cap' image of heavy industry and the monolithic public sector. The risk for the Labour party, like social democratic parties across Europe, is further electoral defeat and then inevitably, permanent irrelevance. As of today, there are few signs that the party grasps why it lost and, in particular, why swing voters in marginal seats were not prepared to vote Labour. A party that does not understand why it was defeated scarcely deserves to be taken seriously by the electorate. This book examines why Labour so overwhelmingly lost the trust of voters, and crucially how the party under a new leader can win them back by 2020 - charting Labour's path to power.
