Labour’s last-minute attempts to secure support from rebellious MPs have unravelled, creating disarray and intensifying pressure ahead of a pivotal welfare vote.

A Labour whip who resigned over disability benefit cuts is urging the PM to consult disabled people and publish a formal review, insisting on clearer welfare reforms before any parliamentary vote.

Under pressure from potential Labour rebellion, the PM softened proposed welfare measures to ensure legislative passage and maintain support within the Commons.

Senior figures are said to be at odds with the leader’s insistence that unrest among party members over proposed welfare measures is “overstated,” prompting speculation that ministers will offer concessions to placate critics.
