UK Prime Minister Under Immense Pressure to Resign

Embattled following the outbreak of a scandal that has shaken the Labour Party’s confidence in him, UK Prime Minister Keir Starmer has continuously resisted calls to resign, vehemently defending his political position as the Scottish Labour Leader Anas Sarwar in fiery language becomes the highest profile of a series of figures to lambast the Prime Minister’s decision-making and repeat demands that he step down.

Peter Mandelson, the former UK Ambassador to the United States, was dismissed from office by Starmer following public revelations of his close relationship to disgraced New York financier Jeffery Epstein, who was convicted of procuring for prostitution a girl below age 18 in 2008, before being indicted in 2019 on charges of sex trafficking, ultimately passing away under suspicious circumstances in his cell in the New York Metropolitan Correctional Center prior to the conclusion of his trial. Epstein’s death was officially ruled a suicide, though significant public sentiment remains behind the theory that his death was a cover-up. New releases of files relating to Epstein’s alleged activities have shown that Mandelson continued his association with the financier even following his conviction for solicitation of a minor. Keir Starmer, who appointed Mandelson as Ambassador, admitted he knew of the relationship between Epstein and Mandelson; however, he downplayed his knowledge of the extent of that friendship. Furthermore, emails released as part of the Epstein files have suggested that Mandelson may have passed sensitive UK government information relating to the 2008 Financial Crisis to Jeffrey Epstein, in addition to receiving pay-offs from him.

The outrage from the incident has been immense. In addition to Mandelson’s departure from government, Morgan McSweeney, the Prime Minister’s Chief of Staff, resigned, but not before claiming that he had urged Starmer to appoint Mandelson as U.S. Ambassador. The Prime Minister’s Communications Director, Tim Allan, who himself was a friend of Peter Mandelson’s and collaborated with him under the Tony Blair Government in the 1990s, likewise resigned, stating, “I have decided to stand down to allow a new No. 10 team to be built,” and “I wish the P.M. and his team every success.”

Starmer has been sent reeling from the loss of two of his most important allies, with Kemi Badenoch, leader of the UK Conservative Party, stating that Starmer’s position is “untenable”. However, with the remainder of his cabinet rallying behind him, the possibility of an internal party coup seems to have abated for the moment. Labour has continued to slide in nationwide polling, with Anas Sarwar’s Scottish Labour suffering immensely for his party’s association with the UK Labour Party of which Keir Starmer is the head. Once neck-and-neck with the Scottish National Party, the long-time ruling party of Scotland, a constituent country of the UK with devolved powers, Scottish Labour is now third, falling behind the SNP and Reform UK, an upstart right-wing populist party led by eurosceptic Nigel Farage, currently an MP but formerly a member of European Parliament known for being the public face of the Brexit campaign, which he led to victory in the 2016 United Kingdom European Union membership referendum, following which the UK announced its intention to withdraw from the European Union, eventually achieving so in 2020. Now seeking a further major political victory, namely dominance over the Labour and Conservative parties in the upcoming UK general election, which by law must be held no later than 2029, Farage has pivoted to opposing the vast majority of UK immigration, likewise adopting a Trumpian economic nationalist approach to the economy. His outreach to disaffected voters, largely the same demographic that backed his approach to Brexit, has paid immense dividends, with Reform set to trounce both Labour and the Conservative Party were elections held imminently.

Worried over the prospect of Labour losing its staggering majority in the UK House of Commons —the lower house of parliament— allegations have swirled that certain members of the Starmer Government, as well as former members, are seeking to challenge Prime Minister Starmer’s party leadership, and in doing so, take over the reins of government. Starmer, who has a shocking 71% disapproval rating according to YouGov, has become the least popular UK Prime Minister since polling began roughly 50 years ago, even beating his predecessor, Rishi Sunak, who, as leader of the Conservatives called a snap election that netted Labour over 200 seats compared to its prior electoral result. These murmurs have centered on two candidates: Health Secretary Wes Streeting and former Deputy Prime Minister Angela Rayner. Both candidates have signaled their unwavering support for Starmer, yet, behind the scenes, have made efforts to build the necessary infrastructure for a leadership challenge.

The first of these individuals, West Streeting, has publicly backed Starmer in the House of Commons, yet publicly has done little to discourage assumptions that he seeks the PM office for himself, with MPs close to him claiming he intends to voice dissent after the Gorton and Denton byelection in late February, a subdivision of Greater Manchester and the second byelection of Starmer’s tenure. The first was won by Reform in a stunning upset against Labour; therefore, if Reform UK were to pull off another upset in an urban constituency like Gorton and Denton, the traditional heartland of Labour, the political shockwaves would likely further doom Starmer’s standing. The Labour Party is under significant pressure to perform well, as even a close election would signal widespread disillusionment with the Prime Minister’s leadership. Streeting, who is described as a Blairite and only slightly to the left of Starmer himself, is seen very much as a continuity candidate, presenting a vision of Starmerism without Starmer. This mundanity may lend itself well to a national electorate that has swung sharply rightwards following the 2024 General Election; however, the Labour Party membership, which would need to advance Streeting to a final runoff, skews to the left of Britons generally, meaning Streeting would have to tow a delicate line in simultaneously uniting disparate interests across his party and country. Despite being a moderate in an increasingly polarized electoral landscape, Streeting still represents Labour Party orthodoxy by advocating for a generous welfare state, particularly in light of impending AI disruptions. He has also noted the rising wealth inequality in Britain, though he has raised objections to the record-high taxation of Chancellor of the Exchequer Rachel Reeves.

Angela Rayner, by contrast, is a darling of the Labour left, winning endorsements from union leaders as a potential high-profile replacement for Starmer. She has also publicly backed the current Prime Minister’s rebuke of his opponents; however she has far less to lose from a leadership challenge than Streeting, who, unlike her, is a sitting cabinet secretary. Rayner resigned from her position as Deputy Prime Minister in late 2025, having been found in breach of the ministerial code after failure to pay the appropriate amount of tax on a property she owns. As with Streeting, it is unlikely any challenge would be mounted prior to the upcoming byelection, with events after February an open question. Rayner enjoys far higher support with the rank and file of the Labour Party, similar to politicians such as Alexandria Ocasio Cortez in the U.S. She has, however, been subject to concerns over broader electability, echoing issues with the tenure of Jeremy Corbyn as Labour leader, whereby he enjoyed immense base support while consistently failing to translate this to a victory at the polls. Streeting and Rayner, in essence, represent opposite currents in the modern Labour movement, one that pits tested moderation against youth progressivism. Which vision of the future will ultimately sway the party remains to be seen.

Starmer, under attack but far from defeated, still wields enormous power over the Labour Party, having decisively crushed the Conservatives in 2024. Whether this authority will translate into continuing backing of his rule depends largely on his skill as a political operator. The Prime Minister has vowed to continue working to implement the Labour Party’s agenda, though many see his departure as a foregone conclusion. For his critics, as well as opportunists within his ranks, the knives are out.

UPDATE: Since the writing of this article, The Labour Party has decisively lost the Gorton and Denton byelection, coming in third place behind the Green Party and Reform UK respectively. This outcome represents a staggering 25 percentage point swing against their outcome in the same constituency just two years ago, handing the Green Party their first parliamentary byelection win in history. Reform, though not victorious, still doubled their 2024 margin. The results of the byelection, and especially the large swing toward the Greens, upset even pessimistic Labour Party predictions, placing even stronger pressure on Keir Starmer to reform his administration or else face the possibility of an intra-party struggle.
