Andy Burnham wins Makerfield by-election, clearing the path to challenge Keir Starmer for Labour leadership.
Keir Starmer faces significant popularity declines, fueling intense speculation of an imminent leadership transition.
The political shift comes amid the rising influence of Reform UK and voter frustration with the established political class.
Burnham's potential premiership would likely signal a shift in the UK's approach to domestic policy and European relations.
