Only three Welsh MPs break ranks as Starmer faces biggest revolt to date

A MAJOR rebellion is erupting inside the Labour Party, with 108 MPs—including Welsh frontbencher Henry Tufnell—signing a motion to block controversial welfare cuts, in what has been described as the biggest internal revolt since Keir Starmer became leader.

The MPs have backed a reasoned amendment that would kill off the government’s new Welfare Reform Bill at its second reading, arguing the proposals would “strip support” from hundreds of thousands of disabled people and low-income claimants across the UK.

Among the signatories is Henry Tufnell, Labour MP for Mid and South Pembrokeshire.

Tufnell’s decision to break ranks has put him on a collision course with party whips and leadership figures, with Angela Rayner warning that Labour MPs who defy the official party line may face disciplinary consequences.

Risking his role

Sources inside Westminster suggest several Labour frontbenchers are now “considering their positions”, and may resign rather than vote against the amendment or abstain.

The vote comes amid widespread concern over the government’s plan to cut £5 billion from welfare spending, including changes to Personal Independence Payments (PIP) and stricter Universal Credit assessments.

Welsh voices divided

Of the 27 Labour MPs representing Welsh constituencies, just three have signed the amendment, highlighting a cautious approach from most Welsh representatives. While their names have not all been confirmed publicly, only Tufnell holds a frontbench post among them.

The Welsh Government has previously criticised UK benefit reforms, but has stopped short of direct confrontation over the latest proposals.

One disability rights campaigner in Cardiff told The Herald: “It’s disappointing to see so few Welsh MPs take a stand. Tufnell should be applauded for putting principle above position.”

The stakes for Starmer

The rebellion is particularly damaging for Keir Starmer, who has tried to present Labour as a party of “discipline and government readiness.” With more than a quarter of his MPs now defying the whip, the amendment has become a litmus test for party unity.

The vote on the bill is expected later this week, and could see Labour leadership punish MPs who support the amendment—potentially withdrawing the whip or removing them from internal positions.

The party has not confirmed whether it will allow a free vote, abstain, or formally oppose the amendment—but the rebellion shows growing backbench unrest over Labour’s positioning on social justice issues.

Why this matters for Pembrokeshire

• If Tufnell is forced to resign, it may weaken local influence in Labour’s policy-making.
• Disability charities in Wales warn that cuts could disproportionately affect rural and coastal communities with fewer support services.
• The row highlights the gap between Labour’s leadership and its grassroots members, especially on issues of poverty and welfare.
