Reform UK has set out plans it says will save more than £50bn a year from the welfare bill by 2030 if it gets into government.
The party believes it can deliver much of this by stopping foreign nationals from getting most benefits and also reforming disability payments while protecting the most "severely disabled".
BBC Verify has been breaking down what Reform says it wants to do - and how realistic it is.
The UK government will spend £353bn on welfare benefits this year - just under half of that goes on the state pension, which Reform has said it will not cut.
That leaves £207bn - so cutting £50bn a year like Reform proposes would represent roughly 25% of total remaining welfare spending, which would be extremely ambitious.
One of the benefits Reform is looking at is Personal Independence Payments (PIP) - a working age payment that helps individuals deal with the extra costs of having a physical or mental health condition or disability.
The number of people claiming it has risen from around 2.4 million before the pandemic to four million this year in England and Wales.
Reform says around £21bn of its planned £50bn savings would come from changes to health and disability benefits including PIP.
While saying those with the most severe disabilities would be protected - Reform said around 2.89 million people in receipt of PIP will be "reassessed over time" which would lead to current payments being "modified or withdrawn" and replaced with its proposed "Disability Needs Assessment".
Analysts warn that these savings are by no means guaranteed. The Institute for Fiscal Studies think tank says there is "relatively little detail" about what Reform's plan entails.
Another big element of Reform's planned cuts comes from taking away benefits from foreign nationals. It claims around £20bn could be saved from its £50bn target if they were banned from getting benefits including Universal Credit (UC).
More than a million UC claimants were born overseas including around 700,000 EU citizens who arrived in the UK before Brexit and have the right to live and work in the country.
It's important to bear in mind that around half of EU citizens claiming UC are in employment.
The government doesn't provide figures for the number of foreign nationals claiming other benefits.
But taking away these benefit rights would not be a simple thing to do because it risks putting the UK on a collision course with the EU.
Around 4.5 million EU citizens have long-term settlement rights in the UK which means they are eligible to claim benefits.
An estimated one million UK citizens living in the EU have similar rights. Stripping EU citizens of their rights could lead to member states retaliating against the UK.
Reform says it would renegotiate the post-Brexit deal that underpins these rights but that would mean re-opening a process that was supposed to have been settled in 2020.
Another wrinkle in Reform's plan is that its planned savings could disappear if a large number of EU nationals apply to become UK citizens and were able to keep their entitlement to benefits.
Reform has said it is considering using a less generous measure of inflation to calculate how much benefits will go up each year to save £4.8bn a year. It also says it wants to spend extra money on tackling benefit fraud which it predicts will save as much as £2.8bn a year. However, other governments have tried to tackle fraud in the past with varying degrees of success.
The party has also pledged that people who are long-term welfare claimants and fit to work would be forced to do 20 hours of work a week in the community on council-run schemes.
It's not clear how this saves significant amounts of money on welfare given it will cost councils money to run the programmes.
Reform is by no means alone among the political parties in proposing welfare reform.
A recent review of the PIP system by Labour minister Sir Stephen Timms concluded it was "not fit for purpose". The government is expected to outline its own reforms later this year.
But analysts stress that achieving significant savings from the welfare bill is easier said than done.
It's also worth bearing in mind the number of PIP claimants in the constituencies of several prominent Reform MPs - such as Boston and Skegness and Ashfield - is higher than the national average.
And in some cases the number of PIP claimants is higher than the size of the MPs' majorities. The same is true of some of Reform's main target seats.
This appears to be a political risk the party is willing to take.

Four leading AI models discuss this article
"Reform’s plan relies on legally dubious and socially explosive assumptions that would likely increase, rather than decrease, net government expenditure through administrative bloat and economic disruption."
Reform’s £50bn welfare cut proposal is a fiscal fantasy that ignores the inflationary and social costs of implementation. By targeting 25% of non-pension welfare spending, they risk a massive surge in homelessness and local authority costs, as councils would bear the burden of 'work-for-benefit' schemes. Furthermore, the £20bn savings from stripping rights from foreign nationals ignores legal constraints and reciprocal agreements, likely triggering retaliatory trade friction. Markets dislike policy uncertainty, and proposing to reopen the Brexit withdrawal agreement is a direct threat to the stability of the GBP and UK Gilts. This is a political narrative, not a credible macroeconomic framework.
If Reform’s aggressive reassessment of PIP claimants successfully shifts millions from economic inactivity into the labor force, it could theoretically address the UK's chronic labor shortages and boost GDP, potentially offsetting the initial administrative costs.
"The £50bn target requires three simultaneous wins (PIP reassessment, EU benefit restrictions, fraud crackdown) that have never been achieved together, and Reform's own electoral geography makes the PIP cuts politically toxic."
Reform's £50bn welfare cut is mathematically aggressive but politically fragile. The 25% reduction in non-pension spending requires £21bn from PIP reassessment (2.89m people) and £20bn from foreign national benefit restrictions. The PIP target assumes successful reassessment of 67% of claimants—the article notes IFS flagged 'relatively little detail.' The foreign national savings hinge entirely on EU renegotiation and avoiding retaliation against 1m UK citizens in the EU. Fraud savings (£2.8bn) are speculative; prior governments underdelivered. The article correctly flags that Reform MPs' own constituencies have above-average PIP claimants—political backlash risk is real. The 20-hour work requirement lacks cost-benefit clarity. Execution risk is extremely high.
If Reform actually wins power and faces civil service implementation teams, the political pressure to protect constituencies and avoid EU trade friction could force a retreat to £20-30bn in real savings—still meaningful and politically defensible as 'welfare reform lite,' making this less a failed promise and more a successful negotiation with reality.
"Achieving £50bn of welfare savings by 2030 hinges on politically and legally fragile reforms (PIP reassessment and foreign-benefit bans) that face court challenges, administrative costs, and cross-party pushback, making the target far from assured."
Reform UK’s plan seeks to cut £50bn from welfare by 2030, tilted toward banning benefits for many foreign nationals and overhauling disability payments. The strongest caveat is execution risk: many reforms are legally delicate (EU/EEA rights, PIP reassessment, and potential court challenges) and politically contentious, especially in marginal seats the party targets. The article glosses over admin costs and offsetting spending rises (fraud detection, council costs for work schemes, potential costs of misclassification). The estimate relies on optimistic assumptions about eligibility, migration, and price indexing; even small slips could blow the 2030 target. The risk that reforms stall or are watered down is high.
One could argue the upside risk is that incremental reforms—fraud controls, tighter indexing, and limited work requirements—could be implemented without major legal blowback and deliver meaningful savings sooner than feared, dampening the bearish case.

"The market will price in the fiscal uncertainty of these proposals long before the actual implementation phase, creating immediate volatility in Gilt yields."
Claude and ChatGPT focus on implementation friction, but both ignore the primary market risk: the 'Gilt Vigilante' response to fiscal instability. If Reform pursues a £50bn cut that triggers trade friction or legal gridlock, the UK’s risk premium will spike. Investors won't wait for 'welfare reform lite' to materialize; they’ll demand higher yields on 10-year Gilts immediately. The real danger isn't that the policy fails, but that the attempt destabilizes the sovereign credit profile.
"Market risk hinges on visible execution failure, not policy boldness—a successful 'lite' reform actually improves sovereign risk perception."
Gemini's Gilt Vigilante risk is real, but the timing assumption is backwards. Markets don't punish *intent*—they punish *execution failure*. If Reform wins and immediately delivers fraud controls + tighter indexing (low-friction wins), Gilts rally on fiscal discipline signals. The destabilization spike happens only if the party *attempts* the £20bn foreign national cut and loses the legal battle publicly. Execution success, not ambition, determines the risk premium.
"Credibility and execution determine gilt moves, not the mere existence of a £50bn welfare reform; an accountable, gradual reform path could stabilize gilts, while only publicized execution failure triggers a sell-off."
I push back on Gemini's 'Gilt Vigilante' claim as an immediate yield spike. Markets care about credible, executable paths. A transparent, gradual reform plan with early wins (fraud controls, tighter indexing) could quell risk premia; the spike would come from execution failure or legal gridlock, not ambition alone. The real risk is political friction delaying reforms and creating uncertainty, not a binary heat-seeking move in Gilts.
