Your Party sees leading figures make the case for Britain's major new political project, laying out the challenges ahead and how to surmount them. Oliver Eagleton interviews Zarah Sultana MP; Leanne Mohamad, who came within 500 votes of unseating Labour's Wes Streeting at the last general election; Stop the War co-founder Andrew Murray; Our Bloc author James Schneider; Andrew Feinstein, who took on Keir Starmer in Holborn and St Pancras in 2024; and former Corbyn speechwriter Alex Nunns.

Delineated in these pages is a left-wing programme opposed to austerity, inequality and war, an agenda fit to oppose both authoritarian centrists and the hard right. The discussion addresses the need to balance parliamentary politics with social movements, short-term aims with long-term ambitions, and centralised structures with grassroots participation.

In his introduction, Eagleton lays bare the abject failure of Starmer's Labour government, explaining why a new socialist party is not only possible but urgently needed. Over 750,000 people have registered to support Your Party. This book is essential reading on the new insurgent force at Westminster and beyond.
