Restoring Control over the Immigration System is a 2025 white paper published by the Starmer ministry on 12 May 2025, outlining comprehensive reforms to UK immigration policy. The 80-page document represents the most sweeping changes to Britain's legal migration framework in over a decade, aimed at significantly reducing net migration and creating what the government describes as a "controlled, selective and fair" immigration system.
The white paper introduces major policy changes across work, study, family and settlement routes, including doubling the qualifying period for citizenship from five to ten years, ending overseas recruitment for care workers, and raising skill requirements for skilled worker visas to graduate level. The reforms are designed to shift away from what Prime Minister Keir Starmer characterised as the previous Conservative government's "one-nation experiment in open borders", which saw net migration rise from 224,000 in 2019 to 906,000 in 2023.
The proposals have generated significant controversy, with Starmer's accompanying speech containing language critics compared to Enoch Powell's 1968 Rivers of Blood speech. Business groups, immigration lawyers and civil society organisations warned the changes could cost employers over £14,000 per sponsored worker and create severe labour shortages in key sectors. The white paper was widely viewed as a response to the rise of Reform UK, which won 30% of the vote in the May 2025 local elections on an anti-immigration platform.
Analysis suggested the controversy had political consequences for Starmer. Research by the New Statesman found that the speech "backfired", showing "a drop in Labour support" with "no modelling scenario where we find the speech has any positive effect". The study found the speech made immigration 3 percentage points more salient and reduced support for all left-of-centre parties by 1.5 percentage points. The apology was described as "another climbdown from Number 10 amid backlash from MPs", with the controversy described as "yet another internal Labour dispute" over Starmer's political positioning on immigration.
Contents According to analysis by the House of Commons Library, the white paper represents "the most sweeping changes to the UK's legal migration framework in over a decade". Legal experts described the document as proposing changes expected to reduce visa issuance by around 100,000 annually and marking "a profound shift in the trajectory of UK immigration policy" from demand-led migration to "a contribution-based, skills-focused model".
Skilled worker visa reforms The white paper proposes significant changes to skilled worker immigration. According to immigration law analysis, the minimum skill level for Skilled Worker visa sponsorship would increase from RQF Level 3 (A-level equivalent) to RQF Level 6 (graduate level), meaning only jobs requiring at least an undergraduate degree would be eligible for sponsorship. This change removes approximately 180 occupations from eligibility and impacts around 111 currently eligible occupations.
Legal commentary noted that the general salary threshold has risen to £38,700, and the Immigration Salary List providing discounts for shortage occupations has been abolished. The Immigration Skills Charge would increase by 32% - the first rise since 2017 - with medium and large employers paying £1,320 per sponsored worker annually.
Care worker visa closure Analysis by immigration experts highlighted the complete restriction of overseas recruitment for social care workers, with new overseas applications for adult social care roles under the Health and Care Worker visa no longer being accepted from 22 July 2025. Legal firms noted that existing care workers in the UK may extend or switch visas until 2028, but this remains under review.
Settlement requirement changes Immigration lawyers identified proposals to extend the standard qualifying period for permanent residence (indefinite leave to remain) from five years to ten years for Points-Based System routes, including Skilled Worker visas. The white paper proposes an "earned settlement" system with a shorter pathway than ten years for people who have made "Points-Based contributions to the UK economy and society", though legal commentary noted that specific criteria are yet to be determined.
Student visa restrictions Education sector analysis highlighted significant changes to student immigration routes. The Graduate Route duration would be reduced from two years to 18 months for international students, with doctoral students continuing to be eligible for a three-year Graduate visa. Legal experts noted that from 2025, only those undertaking PhDs or other advanced research programmes would be permitted to bring dependents to the UK.
Universities UK noted that compliance requirements for universities would be tightened, with sponsoring universities required to maintain an enrolment rate of at least 95% (increased from 90%).
English language requirements Legal analysis identified increased English proficiency requirements across visa categories. Skilled Workers would need to meet level B2 English proficiency (up from B1), and all adult dependants would need to demonstrate English at level A1 for initial applications, A2 for extensions, and B2 for settlement.
"Island of strangers" speech Keir Starmer introduced the white paper with a speech on 12 May 2025 that generated significant controversy due to its language and rhetoric. Media analysis noted that the speech was "widely seen as a reaction to the results of the recent local elections, in which the right-wing party Reform UK won 30% of the vote".
Speech content and rhetoric According to media coverage, Starmer opened his remarks by pledging to "take back control of our borders and close the book on a squalid chapter for our politics, our economy, and our country". Media reports noted his deliberate use of "take back control" from the outset, making clear the intended audience and message.
Political commentary highlighted Starmer's criticism of the previous Conservative government, with coverage noting he stated that between 2019 and 2023, "net migration quadrupled" and "reached nearly 1 million" in 2023. Media analysis noted he declared that "Taking back control is a Labour argument".
Most controversially, academic analysis by David Miller, professor of political theory at Nuffield College, Oxford, noted that Starmer warned that "Without [immigration rules], we risk becoming an island of strangers, not a nation that walks forward together".
According to media reports, Starmer described the UK's immigration system as contributing to forces "slowly pulling our country apart" while stating that immigrants "make a massive contribution" to British society. Political analysis noted that he characterised parts of the economy as "almost addicted to importing cheap labour".
Criticism and controversy The speech generated intense criticism over its language and rhetoric. Katy Brown of Manchester Metropolitan University noted that Starmer's rhetoric "chimes with classic far-right narratives where migration is framed as the root of all societal ills", and suggested the speech contained elements reminiscent of far-right conspiracies about elites deliberately encouraging mass immigration, with Starmer's words potentially acting as a "dog whistle".
David Miller in the New Statesman described the phrase "island of strangers" as becoming "the locus for a vitriolic exchange of views," reading it not as academic philosophy but as echoing Enoch Powell's Rivers of Blood speech, in which Powell championed those who "found themselves made strangers in their own country".
Political and social reactions Civil society groups strongly condemned the language used. Steve Smith, CEO of Care4Calais, called Starmer's language "dangerous," warning that "shameful language like this will only inflame the fire of the far-right and risks further race riots".
Westminster journalists were reported to have grilled Starmer on what they called his "journey" on migration, with critics raising questions about authenticity when he denied changing positions, claiming "core consistency" in his views.
Reactions Political party responses Labour Party The speech provoked intense divided reactions within Starmer's Labour Party.
Diane Abbott, the veteran Labour MP, branded the speech "fundamentally racist", stating: "I was very disturbed to hear Keir Starmer on the subject of immigration... I thought that was a fundamentally racist thing to say. I think Keir Starmer is quite wrong to say that the way that you beat Reform is to copy Reform." The MP Nadia Whittome said that the speech "mimics the scaremongering of the far right," describing Starmer's words as "shameful and dangerous".
Sarah Owen, Labour chairwoman of the Women and Equalities Select Committee, argued that the government should focus on "investing in communities to thrive – not pitting people against each other", warning that "chasing the tail of the right" could put the country on "a very dark path". Welsh Labour leader and Welsh First Minister Eluned Morgan stated that she did not want to be "drawn into a debate where people are using divisive language when it comes to immigration."
Other Labour MPs who criticised the speech included Zarah Sultana, who described the speech as "sickening" and tweeted: "The Prime Minister imitating Enoch Powell's 'Rivers of Blood' speech is sickening. That speech fuelled decades of racism and division. Echoing it today is a disgrace. It adds to anti-migrant rhetoric that puts lives at risk. Shame on you, Keir Starmer." She also questioned whether Starmer's speech had actually been written by Nigel Farage, asking: "Did Nigel Farage write this speech? Dehumanising and divisive. We deserve better than this." Former shadow chancellor John McDonnell, who lost the Labour whip, compared the "island of strangers" reference to "the divisive language of Enoch Powell" and questioned in Parliament: "When the prime minister referred to... an island of strangers, reflecting the language of Enoch Powell, does he realise how shockingly divisive that could be?"
The MP Joani Reid stated that "we are not closing the door on immigration that can boost growth and strengthen the economy. But employers who hope to get away with paying low wages or avoid investment in staff training have had 'time' called today".
The then Parliamentary Under-Secretary of State for Migration and Citizenship, Seema Malhotra, stated that Starmer's speech recognised "how much migration has been and remains a vital part of our identity," saying that unless immigration policy changed "we risk being communities that live side by side, rather than work and walk together." The then Home Secretary, Yvette Cooper, stated that Starmer was "right to say we need to change", adding that "I know that everybody always gets caught up in focusing on different phrases and so on, but we do have to be talking about the policies".
Conservative Party Shadow Home Secretary Chris Philp dismissed Starmer's stance, stating that "Starmer is the same man who wrote letters protesting against deporting dangerous foreign criminals and has overseen the worst ever start to a year for illegal immigrants crossing the channel." He called the idea that Starmer was tough on immigration "a joke" and labelled the failure to impose a cap on numbers "laughable". Conservative critics more broadly argued that Starmer's measures did not go far enough, accusing Labour of adopting ideas they had championed whilst still lacking credible targets and enforcement. Some highlighted the fact that Labour had previously opposed similar restrictions.
