“Writing a book about Jeremy Corbyn, set out with two objectives. The first was simple: to explain how he became the leader of the Labour Party. I was disappointed - but not at all surprised - at the complete absence of intellectual curiosity on display. The second objective I had to try to capture for posterity the excitement and spirit of the first Corbyn campaign. Those moments when the impossible suddenly becomes possible are so powerful to those who experience them. I think it's politically valuable to relive such moments, to learn the lessons of what went right.”
