Corbynistas flock to Zack Polanski's Green Party

politicsApr 3, 2026253

Former Labour allies known as Corbynistas are joining Zack Polanski's Green Party, after he pivoted the party left with an 'eco-populist' pitch. They are defecting because Keir Starmer has moved Labour toward the centre, and has not committed to a wealth tax or stronger anti-poverty measures. The influx has reopened debates within the Greens and online about energy consumption, drug policy, and how accessible party policies are. The shift matters because it could redraw the British left, boost Green membership, and complicate Labour's electoral strategy.
