Labour could have faced electoral wipeout if it went ahead with 拢5billion of benefits cuts according to new research from one of the party鈥檚 own MPs. A dossier compiled by Jon Trickett and shared with the Sunday Mail details 176 seats with a Labour majority less than the number of Personal Independence Payment (PIP) claimants. The veteran parliamentarian used House of Commons data to prepare a report comparing MPs鈥 majorities to the number of disability benefit claimants and Winter Fuel Allowance recipients in their constituencies. Both groups face being hit by cuts aimed at rebalancing the country鈥檚 finances. Prime Minister Keir Starmer has performed a partial u-turn on winter fuel, and last week agreed to limit changes to PIP in the face of a backbench rebellion, however serious concerns remain within the party. According to Trickett鈥檚 research deputy Prime Minister Angela Rayner, health secretary Wes Streeting and Home Secretary Yvette Cooper are among those whose majority was smaller than the number of PIP claimants. In Scotland – where the Scottish Government controls the equivalent benefit to PIP – all but one Labour MP has more winter fuel claimants than their majority. Trickett, said his report 鈥渟hows the enormous damage which the welfare changes would inflict on thousands of disabled including some of the most unfortunate people in every single community.鈥 The MP added: 鈥淚t also shows clearly the potential political damage to the Labour Party from policies that make people worse off, are unjust and which fail to deliver the positive change people need. 鈥淭he PM finally saw that he needed to find reverse gear. However the current proposals don鈥檛 go far enough and we need wiser counsel to put matters right. 鈥淭he battle for justice is not yet over.鈥 The Prime Minister had to make concessions to the welfare bill as more than 100 of his own MPs backed an amendment that would have effectively killed it. Speaking to the Welsh Labour conference yesterday Starmer promised to reform welfare 鈥渋n a Labour way鈥 and said his party wouldn鈥檛 鈥渢ake away the safety net that vulnerable people rely on鈥. DWP Secretary Liz Kendall confirmed on Friday that existing PIP claimants wouldn鈥檛 be affected by new eligibility criteria due to come into force in April 2026. The health element of Universal Credit, given to those with disabilities or health problems affecting their ability to work, will be halved to around 拢200 a month for new claimants. Existing claimants and those with terminal or life-long and severe illness will be exempt. Despite the changes some Labour MPs are still not satisfied and will continue to oppose the plans when they come before the Commons on Tuesday. Grangemouth MP Brian Leishman said: 鈥淚t sounds to me like it will be the creation of a two-tier welfare system. That is completely unacceptable. There has not been any consultation with organisations and charities. 鈥淲e鈥檝e got to have a proper system that is caring and compassionate and meets people鈥檚 needs. That is not what they are offering with these concessions. 鈥淚 have not changed my mind. I hope the reasoned amendment will still be there and it gets selected. If not then I will be voting against the government.鈥 Disabled people in Scotland don鈥檛 receive PIP, instead getting Adult Disability Payment directly through the Scottish Government although it is funded via the block grant from Westminster. Labour鈥檚 changes would have a direct impact on the Scottish Government鈥榮 funding with Holyrood ministers likely to have to make cuts to Scotland鈥檚 benefits bill as well. Senior Scottish Labour sources fear the government鈥檚 very public concessions on the welfare reforms and winter fuel payments as well as their refusal to compensate WASPI women could damage them at the next Holyrood election. One MSP said: 鈥淭his has been a disaster and makes us look completely incompetent. When the Prime Minister is lurching from one position to another on major policies it looks as though he doesn鈥檛 know what he鈥檚 doing. 鈥淚鈥檇 be surprised if this mess didn鈥檛 have an effect next year for us.鈥 Trade unions have also spoken out against the reformed welfare bill, with Unite General Secretary Sharon Graham calling for it to be scrapped completely. Scotland鈥檚 most senior trade union leader, the STUC General Secretary Roz Foyer told the Sunday Mail the plans were a 鈥減ernicious attack鈥 on vulnerable people. She said: 鈥淭hese welfare reforms from Labour might as well have been typed on a Tory letterhead. 鈥淚n no way is this the 鈥榗hange鈥 that voters were promised during the election. 鈥淚rrespective of the Bill鈥檚 fate, with inequality growing, billionaires getting richer and working people finding it harder to keep their heads above water, it鈥檚 incredulous that a Labour Government would make carers, the sick and disabled their first targets for so-called reform. 鈥淎lmost 400,000 people look set to fall into poverty as a result of this pernicious attack, 50,000 of whom are children. 鈥淭here will also be a clear knock-on effect to the Scottish Government鈥檚 ability to mitigate yet more UK Government austerity. 鈥淭hese are neither Labour values nor the values of the Labour movement.鈥 SNP Westminster leader Stephen Flynn called for Scottish Labour MPs to vote against the plans while Citizens Advice Scotland said the government鈥檚 concessions were 鈥渘owhere near enough鈥. Of Scotland鈥檚 37 Labour MPs, 10 signed an amendment to the original bill which would have stopped it progressing. Since the concessions were announced, only Leishman has declared he will continue to oppose the bill with the other nine Labour MPs failing to respond to requests from the Sunday Mail.
