Keir Starmer's welfare reforms face an uncertain future as Labour rebels prepare for a crucial vote that could mark the prime minister's first Commons defeat. Despite a last-minute deal between government officials and leading rebels last week, the outcome remains in doubt, with Labour MPs warning on Monday that they cannot support the bill in its current form.
The controversy centres on a new four-point system for qualifying for Personal Independence Payments (PIP), which is set to take effect in November 2026 regardless of a government review. Many Labour MPs are angry that the system will proceed without considering the review's findings, leading to widespread opposition within the party.
Labour whips spent Monday calling colleagues to gauge support, but the rebellion is diffuse, with no single leader. The opposition comes from a large and disparate group, making it difficult for party managers to secure the vote. Six key figures, both inside and outside Parliament, are being closely watched for their influence on the outcome.
