Demolishing the Blairite opposition in 2015, Jeremy Corbyn saw off an attempted coup against his leadership under the banner of the "e;soft left"e; one year on. This unassuming antiwar socialist now leads Labour with a huge mandate. For the first time in decades, socialism is back on the agenda-and for the first time in Labour's history, it defines the leadership.This book tells the story of how Corbyn's rise was made possible by the long decline of Labour and a deep crisis in British democracy. It surveys the makeshift coalition of trade unionists, young and precarious workers, and students who rallied to Corbyn. It shows how a novel social media campaign turned the media's "e;Project Fear"e; on its head, making a virtue of every accusation thrown at him. And finally it asks, with all the artillery that is still ranged against Corbyn, given the crisis-ridden Labour Party that he has inherited, the devastating impact of the coup attempt and the fall-out from Brexit, what it would mean for him to succeed.
