Why Keir Starmer's Landslide Government Is Fighting for Survival

Less than two years ago, Keir Starmer walked into Downing Street with a 174-seat majority, one of the largest in modern British history. On paper, he commanded more political capital than any Labour leader in decades. And on paper is just about where that capital stayed.

Before the year was out, he was already sinking in the polls. By the start of 2026, there were serious whispers inside Westminster about whether he would even survive to face the next election. Then came the Peter Mandelson scandal, centred on Starmer’s former ambassador to the United States, who was revealed to have been deeply connected to Jeffrey Epstein in the latest release of 3.5 million pages of documents.

All of which raises an obvious question: how did a Prime Minister with this kind of majority end up fighting for his political life before his second year was over? And, perhaps more importantly, can his premiership survive? The story of Starmer’s decline is less the tale of a single fatal scandal than of a landslide that was always weaker than it looked, eroded by self-inflicted wounds and finally cracked open by a vetting failure he cannot explain away.

Key Takeaways

Labour’s 2024 landslide of 411 of 650 seats rested on a split right-wing vote, not a surge of national enthusiasm; the party underperformed its 2017 popular-vote share by more than six points.
An October 2024 budget delivering the largest single tax package since 1993, paired with welfare cuts, broke a manifesto promise and squandered Starmer’s early goodwill.
Starmer drove net migration down nearly 70% to around 204,000, yet voters still trust Reform UK more on immigration, and his restrictionism alienated the left.
By early 2026, polling projected Labour collapsing from 411 seats to just 85, with Reform UK on course for an outright majority.
The released Epstein files showed Mandelson allegedly feeding confidential government information to a convicted sex offender, turning a personnel scandal into a question of what Starmer knew.
A two-page Cabinet Office vetting note flagged the Epstein relationship before the appointment, and the Foreign Secretary and security services reportedly raised concerns that were set aside.
Labour has no enforceable mechanism to remove a sitting leader, so the immediate threat has passed, but by-elections and May’s council elections could force the issue.

A Landslide Built on Sand

That Keir Starmer and his Labour Party are in trouble is not breaking news. He has long been underwater in approval ratings. In November 2025, Opinium found that 55% of voters wanted the Prime Minister to resign, with some surveys placing him below even Liz Truss. Conversations about whether he would survive to the next election were already circulating in Westminster before any scandal arrived.

What makes this extraordinary is the 2024 result. Labour won 411 of 650 seats, handing Starmer a 174-seat majority, bigger than Thatcher’s best in 1983 and Johnson’s in 2019, and only a few seats short of Blair’s 179-seat triumph in 1997. By every measure of parliamentary arithmetic, it was a generational mandate, the kind of victory that is supposed to insulate a leader for a full term and beyond.

The Numbers Behind the Mirage

The good news stopped at the seat tally. Despite the landslide, Labour barely improved on its 2019 vote, an election it lost badly, and fell more than six points short of its 2017 high-water mark of 40% of the popular vote. The chamber looked transformed; the country had barely moved.

The explanation lies in the mechanics of the electoral system. The right-wing vote fractured between Rishi Sunak’s Conservatives and Nigel Farage’s Reform, and in the United Kingdom’s first-past-the-post system, often all it takes to win a thumping majority is for your opponent’s vote to split. The 2024 landslide, in other words, had very little to do with Labour itself. Starmer entered Downing Street with a measure of goodwill, but a mandate this thin left almost no margin for error.

He proceeded to spend that goodwill quickly.

The Budget That Broke the Bond

The first and arguably most damaging blow was self-inflicted. Labour’s manifesto explicitly promised not to raise taxes on working people, a pledge Chancellor Rachel Reeves had repeated on multiple occasions. So when the first budget landed in October 2024 carrying the largest package of tax increases in a single proposal since 1993, the backlash was intense. Labour framed it as fiscal responsibility, a necessary answer to the mess the Conservatives had left behind. Voters did not buy it.

The tax rises came alongside divisive welfare cuts, including the removal of the winter fuel allowance for most pensioners, a universal benefit introduced by Gordon Brown. Taking money from people, unsurprisingly, tends to be unpopular. The promise-versus-reality gap mattered as much as the policy itself: a government that had campaigned on protecting working budgets was now seen reaching into them, and the trust it spent in those first months proved impossible to recover.

A Chancellor in Tears and a Welfare Revolt

By summer 2025, the picture was darkening further. A welfare reform package meant to showcase Labour’s willingness to make tough choices collapsed when backbenchers revolted, forcing Reeves into a humiliating U-turn. A government with a 174-seat majority being defeated by its own MPs was a vivid signal of how shallow Starmer’s authority over his party had become.

The symbolism grew sharper still. Asked directly in the Commons during Prime Minister’s Questions whether Reeves would still be Chancellor at the next election, Starmer declined to say yes, with Reeves visibly in tears on the bench just behind him. The moment crystallised an impression of a leadership team under strain and unable to project even basic mutual confidence, and images of a weeping Chancellor did the kind of political damage no rebuttal could undo.

Winning the Argument, Losing the Trust

Then there is immigration, and here the story turns genuinely strange. By any objective measure, Starmer’s government has been more pro-enforcement than its Conservative predecessor. In May 2025 it published a white paper titled “Restoring Control Over the Immigration System,” introducing some of the most restrictive changes to the visa regime in years, tightening English-language requirements across the board, and moving to cancel automatic settlement rights after five years in the country.

It worked. Net migration fell to around 204,000 by mid-2025, down nearly 70% from the record peaks under Sunak. Yet none of it seemed to register with voters. Starmer pushed Labour further toward immigration restrictionism than any leader in the party’s modern history, to little electoral reward.

The disconnect is striking: a Reform Party now stocked with ex-Conservative MPs such as Suella Braverman, figures who presided over the biggest immigration wave in British history, is somehow regarded as more trustworthy on the subject than the man who actually cut the numbers.

Caught Between Two Flanks

The deeper problem is that Starmer’s immigration stance won him no friends on the right while alienating supporters on the left. For many on his own side, watching their party shift in a restrictionist direction felt like voting left and getting Farage as Prime Minister, and they have openly lamented what they describe as Starmer’s divisive language on the issue.

This is the trap of a coalition built on a split opponent rather than a shared conviction. There may be no available position on immigration that satisfies both the voters Reform is courting and the activists Labour needs to keep, and Starmer appears to have found the spot that satisfies neither. By early 2026 the cumulative effect was clear.

The seven-poll moving average put Reform UK at 29, Labour at roughly 20, and the Conservatives at 19. Averaged out, the projection had Labour collapsing from 411 seats to just 85 if an election were held immediately, with Reform winning an outright majority. The party that had stood on the steps of Downing Street with a generational majority was now trailing one that had existed in its current form for less than a decade, and the scandal that would come to define the premiership had not yet broken.

The Appointment That Made Sense at the Time

Starmer was already on weak footing entering 2026 when the Mandelson affair turned a difficult situation into an emergency. Back in 2024, he had appointed Peter Mandelson, one of the architects of Blair’s New Labour and a long-divisive figure within the party, as Britain’s Ambassador to the United States. The Washington posting is always a marquee pick for an incoming Prime Minister, given the closeness of the London-Washington relationship.

At the time, the logic held together. Mandelson had served as the European Union’s trade commissioner, carried deep connections in Washington, and was widely regarded as a highly effective operator. With the constant threat of Trump’s on-again, off-again tariffs hanging over everything, Starmer wanted someone able to navigate the personality-driven channels of Trump’s White House. On its own terms, choosing an experienced fixer for a volatile counterpart was a defensible call.

What the Files Revealed

Then, in September 2025, emails surfaced showing that Mandelson had maintained a close friendship with Jeffrey Epstein well after Epstein’s 2008 conviction for soliciting a minor for prostitution, a connection the Financial Times and the Daily Mail had previously reported but which drew little attention until the wider Epstein controversy returned to the headlines. Starmer sacked him immediately. The matter seemed closed.

It was not. On 30 January 2026, the US Department of Justice released more than 3.5 million pages of Epstein-related documents, and the situation transformed entirely. The files did not show a friendship that had simply lingered too long. They showed a sitting Cabinet minister systematically feeding confidential government information to a convicted sex offender, and doing so with disturbing regularity.

The distinction matters: an embarrassing association is a personnel problem, but the alleged conduct in the files pointed toward something far closer to corruption at the heart of government.

Wall Street, Whitehall, and a 75,000-Dollar Trail

The specifics are striking. Mandelson was revealed to have advised JP Morgan’s Jamie Dimon to “mildly threaten” the Chancellor of the Exchequer over a proposed bank bonus tax, using Epstein as a back channel between Wall Street and Whitehall. It got worse. In 2010, Mandelson wrote to Epstein, a financier whose entire career was built on trading, telling him that sources indicated a 500 billion euro bailout was almost complete.

The very next day, European governments announced the rescue package, and the euro posted its biggest rally in years.

Pair those emails with the roughly 75,000 dollars in payments that financial records show flowing from Epstein-linked accounts to Mandelson, and the picture begins to resemble something a court might one day have to weigh. The Metropolitan Police announced a criminal investigation into Mandelson for misconduct in public office and searched his properties, by which point he had resigned from both the House of Lords and the Labour Party. To many this looked like too little, too late, because the question now dominating British politics was not what Mandelson had done. It was what Starmer had known.

The Warnings He Read and Set Aside

The answer, it turned out, was quite a lot. Before the appointment was even announced in December 2024, Starmer had read a two-page Cabinet Office vetting note that explicitly flagged the Epstein relationship as a risk. It noted that the contact had continued after the conviction, that there was a photograph of the two men together, and that evidence suggested Mandelson had stayed at Epstein’s Manhattan apartment while Epstein was serving his prison sentence.

Starmer put three direct questions to Mandelson: why the contact had continued, why he had stayed at the property, and whether he had ties to a “charity” linked to Ghislaine Maxwell, Epstein’s partner in crime. According to Downing Street, Mandelson repeatedly lied in response, though he disputes this and insists his answers were genuine. Number 10 sources described him as having been “economical with the truth.”

On the property question, Mandelson told Downing Street he had not stayed at the apartment while Epstein was imprisoned, despite the vetting note Starmer had already read flagging evidence to the contrary. Nor was Mandelson’s answer the only ignored warning: the Foreign Secretary, David Lammy, reportedly had concerns, and security services allegedly shared reservations of their own. The team treated the matter as settled and moved on.

An Anger Impossible to Dispel

That decision is what turned an inquiry into Mandelson’s relationships into an existential crisis for the Prime Minister. Once the files dropped and the scale of the conduct became public, attention fixed squarely on Number 10, and on why Starmer had appointed a man whose red flags were known well before the appointment cleared.

“None of us knew the depths and the darkness of that relationship,” Starmer told the public, apologising to Epstein’s victims. On one level that is true: nobody definitively knew about the forwarded government documents or the bailout tip-offs until January. But the public anger is not really about Mandelson’s alleged corruption.

It is about the sense that Britain is governed by an incompetent figure surrounded by a self-serving elite, one that keeps handing jobs and perks to its own members even when they have been advising the most notorious sex offender in modern history. That kind of anger is almost impossible to dispel, because it is no longer about a single appointment but about a whole governing class.

Going Down Fighting

“I have won every fight I’ve ever been in. I’m not prepared to walk away from my mandate.” That was Starmer addressing the Parliamentary Labour Party on 9 February 2026, and he is not backing down without a struggle. Once the dust settled, the cabinet fell into line, with potential challengers including Angela Rayner, Wes Streeting, Ed Miliband, and Andy Burnham all issuing statements of support.

Whatever one makes of him, Starmer is more or less right about the fighting. He waged a serious uphill battle simply to become party leader, and that proved a relative cakewalk next to what followed. He overhauled Labour from the inside out, implementing the controversial recommendation of the Equality and Human Rights Commission’s damning report on Labour antisemitism, dismantling the party’s organisational infrastructure, and ousting former leader Jeremy Corbyn. The rights and wrongs of that are debatable; what is not is that, beneath the boring exterior, Starmer is plainly a man who relishes a scrap.

Why Labour Cannot Easily Remove Him

He is helped, too, by the fact that Labour has few tools to remove him. Unlike the Conservatives, the party has no enforceable mechanism to oust a sitting leader. Conservative MPs can trigger a no-confidence vote with just 15% of the parliamentary party signing on, then remove the leader by simple majority. Labour’s equivalent is purely for show.

The party has used it before. In 2016, shortly after Corbyn became leader, concern about how controversial he was and the damage he might do in a general election prompted a vote. He lost heavily: 172 against him, with only 40 pledging support. Corbyn ignored the result entirely, and that was that. Labour’s position today resembles that of the US Democrats after Biden’s disastrous 2024 debate, saddled with an unpopular leader but lacking any mechanism to remove him unless he chooses to step down himself.

Temporary, With Heavy Lifting

So the immediate threat to Starmer may have passed. Analysts have called his position “temporarily stabilised,” but the word temporary is doing an enormous amount of work. MPs may lack a legal route to force him out, yet pressure can still build from outside. A by-election in Gorton and Denton on 26 February 2026, in what has historically been a safe Labour seat, is heating up, with the party squeezed by Reform on the right and the Greens on the left.

Then come the local council elections in May. If those results match the polling, the pressure to step down would be hard for any leader to withstand.

Even so, the question of who replaces him has no obvious answer. Angela Rayner led among party members last year and would beat Starmer head-to-head, but she resigned over an unpaid stamp duty dispute in September and may still face an unresolved tax inquiry. Wes Streeting and Andy Burnham are alternatives, yet much of what ails Labour in the polls cannot be fixed by swapping the leader.

The Lesson the Tories Already Learned

The underlying problems belong to Britain as a whole, and they will not vanish simply because a new face stands at the dispatch box. The Conservatives can attest to this better than anyone. Between 2022 and 2024 they cycled through three prime ministers in two years without arresting their terminal decline.

Whether the greater risk lies in changing course or in staying it is a question Labour will have to answer for itself. But the party would do well to remember that the “just replace the person at the top” approach the Conservatives embraced so enthusiastically was part of what handed Labour its current majority in the first place. The deepest danger for Starmer may not be the scandal at all, but the possibility that no successor could do any better, leaving a wounded leader presiding over a party with nowhere to turn.

Frequently Asked Questions

How large was Labour’s 2024 majority, and why was it misleading? Labour won 411 of 650 seats, a 174-seat majority larger than Thatcher’s in 1983 or Johnson’s in 2019. But the party barely improved on its 2019 vote share and fell more than six points below its 2017 mark of 40%. The lopsided result owed mainly to the right-wing vote splitting between the Conservatives and Reform under first-past-the-post, not to a surge of support for Labour.

What triggered the early collapse in Starmer’s popularity? The October 2024 budget delivered the largest single package of tax increases since 1993, breaking a manifesto pledge not to raise taxes on working people. It was paired with welfare cuts, including scrapping the winter fuel allowance for most pensioners. A failed welfare reform package, a backbench revolt, and a forced U-turn by Chancellor Rachel Reeves deepened the damage.

Did Starmer actually reduce immigration? Yes. His government’s May 2025 white paper, “Restoring Control Over the Immigration System,” introduced some of the most restrictive visa changes in years. Net migration fell to around 204,000 by mid-2025, down nearly 70% from the peaks under Sunak. Despite this, voters continued to trust Reform UK more on immigration, and the restrictionist turn alienated parts of Labour’s left-leaning base.

What did the released Epstein files reveal about Peter Mandelson? The 3.5 million pages released by the US Department of Justice on 30 January 2026 indicated that Mandelson, while a sitting figure, fed confidential government information to Epstein. He allegedly advised JP Morgan’s Jamie Dimon to pressure the Chancellor over a bank bonus tax and, in 2010, tipped Epstein off that a 500 billion euro bailout was nearly complete the day before it was announced. Financial records show roughly 75,000 dollars flowing from Epstein-linked accounts to Mandelson.

What did Starmer know before appointing Mandelson? Before the December 2024 announcement, Starmer read a two-page Cabinet Office vetting note flagging the Epstein relationship, including that contact continued after the conviction and that Mandelson appeared to have stayed at Epstein’s apartment during his imprisonment. Starmer questioned Mandelson directly; Downing Street says he lied, which he disputes. The Foreign Secretary, David Lammy, and security services reportedly raised concerns that were set aside.

Can Labour force Starmer out? Not easily. Labour has no enforceable mechanism to remove a sitting leader, unlike the Conservatives, who can trigger a no-confidence vote with 15% of MPs. Labour’s internal route is largely symbolic; when it was used against Corbyn in 2016, he lost the vote 172 to 40 and simply ignored it. Starmer can therefore stay unless he chooses to resign.

What could still end Starmer’s premiership? External pressure rather than internal mechanics. A by-election in Gorton and Denton on 26 February 2026 and the local council elections in May are early tests. Poor results matching current polling, which projects Labour falling from 411 seats to about 85, could make his position untenable, though no clear successor has emerged.
