Good news: the solutions to our problems already exist.

Great news: a once-in-a-generation appetite for change means we can make them happen.

- How do we provide affordable housing for everyone?

- How do we rein in the power of Big Tech?

- How do we tackle the climate crisis?

- How do we really give people back control?

For the past four years, Ed Miliband has been discovering and interviewing brilliant people all around the world who are successfully tackling these problems, transforming communities and pioneering global movements. From a citizens' assembly in Mongolia to the UK's largest walking and cycling network in Greater Manchester, from flexible working in Finland to the campaign for the first halal Nando's in Cardiff, Go Big draws on the most imaginative and ambitious of these ideas to provide a vision for how to remake society.

The challenges we face are daunting, but in Go Big he shows that the scale of what is possible is far greater. We are at a rare moment in history when people everywhere see the need for big change. The future is not yet written. It's our job to write it.
