Sir Keir Starmer and his Cabinet could face electoral wipeout as new polling suggests a Left-wing challenge led by Jeremy Corbyn and the Greens threatens dozens of Labour seats.
Labour secured 411 seats at last year’s general election, but fresh analysis by More in Common indicates this would collapse to just 126 if a vote were held this autumn.
Up to 52 Labour constituencies are at risk from Green Party candidates and independents aligned with Mr Corbyn and Zarah Sultana’s new party, many of them within a five-point margin.
Support for a Corbyn-Green alliance stands at 31% of the electorate, rising to 52% among 16 to 34-year-olds.
Anger over the Israel-Gaza conflict has become a central issue, with Corbyn and Green leader Zack Polanski both accusing the Prime Minister of failing to condemn Israel for genocide.
Starmer’s personal ratings have slumped, damaged by scandals over Angela Rayner’s tax affairs and Lord Mandelson’s links to Jeffrey Epstein.
His approval score now sits at -42%, only slightly better than Boris Johnson’s at the point of his resignation.
Polling shows the Prime Minister’s own Holborn and St Pancras seat is under threat, with Labour just three points ahead of a Left alliance.
Cabinet colleagues are also vulnerable like; Home Secretary Shabana Mahmood trails by five points in Birmingham Ladywood, while an independent is projected to oust Health Secretary Wes Streeting in Ilford North.
The threat comes as Starmer prepares to recognise Palestinian statehood at the UN General Assembly. Critics accuse him of seeking to placate Labour’s Left flank, while the US has warned recognition risks rewarding Hamas.
Meanwhile, Corbyn and Sultana’s fledgling party has already been hit by infighting, even as its leaders denounce Labour as morally bankrupt over its stance on Gaza.
