Overview

• Zarah Sultana has officially resigned from the Labour Party and will co-lead a new left-wing movement with Jeremy Corbyn and other independent MPs
• Jeremy Corbyn confirmed he is in talks to form the new party after accusing the government of failing to deliver expected change
• A More In Common poll suggests the nascent party could attract roughly 10% of the national vote, drawing support from Labour, the Greens and the SNP
• The split follows a major backbench revolt that forced the government to abandon key welfare reform measures, highlighting deep divisions within Starmer’s ranks
• Political analysts warn the hard-left breakaway could fragment the centre-left vote and undermine Labour’s parliamentary control
