The Euston Manifesto /ˈjuːstən/ is a 2006 declaration of principles by a group of academics, journalists and activists based in the United Kingdom. The statement was a reaction to what the writers argued to be widespread violations of left-wing principles by others who were commonly associated with the Left. The manifesto states that "the reconfiguration of progressive opinion that we aim for involves drawing a line between forces on the Left that remain true to its authentic values, and currents that have lately shown themselves rather too flexible about these values".
