Prime Minister Keir Starmer faces a significant challenge to his leadership in the UK as over 120 Labour MPs, including some ministers, rebel against his proposed welfare reforms. These reforms aim to save £5bn by reducing benefits for disabled individuals and limiting Universal Credit. As Labour grapples with internal strife, Starmer insists on pressing forward, despite the risk of relying on Conservative support to pass legislation. This political battle underscores the tensions within UK's Labour Party concerning fiscal policy and welfare state sustainability.
