London former Labour council leader defects to Greens [Green Party] Southwark councillor [James McAsh][1] has defected to the Green Party from Labour with a blast at Starmer’s factionalism and red-Tory austerity politics. McAsh was [elected as council leader in July 2025][2], but the central party [moved to quash the result][3] and installed a tame Starmeroid. In his resignation from Labour, McAsh said that he can no longer ask Southwark residents to vote for Starmer’s party because the Labour-run council is: > planning for funding gaps larger than those faced in almost every year of Conservative and Liberal Democrat austerity, this time imposed by a Labour government. > > Unless something changes, Labour cuts will devastate the local services that as residents of this fantastic borough, we all rely on. McAsh added: > I grew up in a Labour household and I’ve devoted much of my adult life to the party. I’m proud of the work I’ve done in Southwark – but Labour is no longer the vehicle for social justice I once thought it was. He is the fourth Southwark Labour councillor to join the Greens since last year’s scandal and the seventh to resign from Labour. Southwark is part of a [London-wide phenomenon of Labour councillors flooding to the Greens][4] since Zack Polanski won that party’s leadership — including [at least one deputy mayor][5]. *Featured image via [SouthworkNews][6]* By [Skwawkbox][7] [1]: https://www.instagram.com/greenjamesmcash/ [2]: https://southwarknews.co.uk/news/community/exclusive-sarah-king-confirmed-as-next-leader-of-southwark-amid-allegations-by-rival-over-election-integrity-and-with-three-councillors-threatening-to-quit/#:~:text=But%20her%20confirmation%20is%20unlikely,ensure%20proper%20procedure%20was%20followed.
