London has always been a city people love to argue about, but according to its mayor, much of that argument has stopped being honest. Sadiq Khan has accused politicians, online bots and foreign state actors of deliberately fuelling a false and damaging picture of the capital, using the tools of the “outrage economy” to turn London into a symbol of decline. His comments came in response to an independent study by the Policy Institute at King’s College London, titled London has fallen? Misperceptions of crime, race, religion and life in the UK capital, which found that public beliefs about the city are wildly out of step with reality. For too long, Khan argued, people have profited from spreading poison online, from algorithms that reward anger and from “rage baiting” narratives that paint London as broken. Yet the evidence tells a very different story. Londoners are less likely to be victims of violent crime than people elsewhere in England and Wales, the murder rate is at its lowest since records began, and the city ranks among the safest major urban centres in the world. But the myths keep spreading. The study found that ordinary members of the public believe crime is far more common than it actually is, that the Muslim population is more than twice its real size, and that large parts of London are effectively no-go zones under Sharia law. These are not harmless misunderstandings. They shape the way people vote, the way communities are judged, and the way the country sees its own capital. Khan’s response was personal and defensive, but also data-driven: he insisted that the “greatest city in the world” is being deliberately talked down by forces that have little interest in the truth.
The gap between perception and reality is nowhere starker than in attitudes to crime. When researchers asked people how many Londoners had personally experienced crime between October 2024 and September 2025, the typical respondent guessed 30 per cent. The actual figure was 12.2 per cent. Even Londoners themselves overestimated the problem, putting the figure at 25 per cent — more than double the real number. Half of those surveyed believed London had the highest rate of violent crime in England and Wales, but in fact the capital had the lowest rate. Similarly, 37 per cent of people thought London had the highest rate of sexual offences, when in reality it was joint-lowest. Homicide figures were equally striking: London recorded its lowest homicide rate per head since records began, and the rate is lower than in Paris, Brussels, Berlin, Madrid and every major US city. None of this means the city is perfect. Between 2019 and 2025, overall crime in London fell by 1.4 per cent, but some categories did rise. Shoplifting and theft from the person more than doubled, and sexual offences and violence against the person also increased. Those are real problems affecting real people, and they deserve serious attention. But the study’s central finding is that public perception is not merely out of date or slightly exaggerated; it is fundamentally disconnected from the evidence. People are not just saying London has a crime problem. They are saying London is drowning in crime, that nowhere is safe, that the capital is uniquely dangerous. That is not what the data shows, and the researchers argue that this persistent negativity has consequences for how the whole country thinks about its largest city.
The same distortion appears in attitudes to religion and diversity. The median public estimate of London’s Muslim population was 35 per cent, but the real figure is 15 per cent. One in three respondents also believed there are areas of London where Sharia law dominates and non-Muslims cannot enter — a claim for which there is no evidence, but which has become a familiar feature of online commentary and political rhetoric. The study suggests these beliefs are not random mistakes. They are part of a broader narrative in which London is portrayed as a city that has lost its character, been overwhelmed by immigration, and become hostile to its own residents. The reality, of course, is far more complicated and far more hopeful. London is one of the most diverse cities in the world, and polling consistently shows that Londoners themselves are broadly comfortable with that diversity. But the idea of “no-go zones” taps into deeper anxieties about identity, security and belonging, and it is an idea that travels easily across borders and through social media. The researchers found that these misperceptions are not evenly spread across the population. Supporters of Reform UK had the most inflated estimates of London’s Muslim population, with a median guess of 50 per cent. They also estimated that 40 per cent of Londoners had experienced crime — more than three times the actual figure — and 87 per cent wrongly believed that total crime in the capital had risen since 2019. Conservative supporters also tended to overestimate crime and the Muslim population, while supporters of Labour, the Liberal Democrats and the Green Party were more likely to underestimate some crimes that had actually increased. In other words, every political tribe has its own blind spots, but the most negative views of London are consistently found on the right.
The study also exposes how much the capital’s wider standing is underestimated. London was ranked first in the 2025 World’s Best Cities index, yet only six per cent of respondents thought it ranked first among the eight major cities tested. Londoners and non-Londoners alike seem reluctant to acknowledge the city’s global success. The same is true of its economic contribution. London is one of only two parts of the UK that runs a fiscal surplus, meaning it pays more in tax than it receives in public spending. That money helps support public services across the rest of the country, but only 30 per cent of respondents knew this. It is a strange situation: the city that subsidises the national economy is often portrayed as a drain on it. This is not just about pride or reputation. If people believe London gets more than its fair share, they are more likely to support policies that cut its funding or reduce its autonomy. If they believe London is dangerous, they are less likely to visit, invest, study or work there. And if they believe London is controlled by foreign interests or held hostage by religious extremism, they are more likely to see its problems as evidence of national decline rather than as challenges that can be managed. Professor Bobby Duffy, director of the Policy Institute at King’s College London, described the capital as “a lightning rod in our national debate.” The repeated claim that “London has fallen” has become a fixture of political, media and social media narratives, even though it does not survive contact with the evidence. As Duffy put it, people do not just have different opinions about London; they are “working from different facts” about it, and those facts are often far too negative.
Sadiq Khan responded to the findings with a mixture of anger and defiance. He pointed to the investment his administration has made in policing and prevention, noting that neighbourhood crime in London has fallen by 14 per cent. He highlighted 14,000 fewer phone thefts and a doubling of officers working in central London. He also stressed that falling crime does not mean the problem has been solved. “One crime is one too many,” he said, adding that he remains committed to investment in frontline policing alongside prevention and intervention through London’s Violence Reduction Unit. That unit takes a public-health approach to violence, treating it as a disease that can be prevented rather than simply punished. It is the kind of long-term strategy that rarely makes headlines, but which Khan says has helped reduce violence without sacrificing the city’s progressive values. His broader message was aimed at those who, in his words, are “deliberately driving these misconceptions for their own gain.” He accused foreign state actors, politicians and bots of using London as a target for organised disinformation, exploiting the algorithms that amplify outrage and the economic incentives that reward division. It is a strong claim, but the study gives it some support: the gap between perception and reality is too large and too consistent to be explained by simple ignorance. There is an industry of London-bashing, much of it online, and it is having a measurable effect on what people believe. Khan’s response was not just a defence of his own record. It was a defence of the city itself, of its openness, its diversity and its resilience. “I’m proud that we are the greatest city in the world,” he said. “As mayor, I will always stand up and defend our liberal, progressive, caring capital.”
What makes this study so powerful is not just the statistics, but what they reveal about the emotional relationship between Britain and its capital. London is not a distant abstraction; it is where millions of people live, work, study and raise families. It is also a symbol — of power, of wealth, of diversity, of change — and symbols attract both love and resentment. The myth that London has fallen is appealing because it offers a simple explanation for complex anxieties: if the capital is failing, then the country is failing, and the blame can be placed on elites, immigrants, or the city itself. But the evidence suggests otherwise. London is safer than many smaller cities. It is more diverse than many people imagine, but less divided than the myths suggest. It is economically vital, culturally influential, and internationally admired. It is also imperfect, and its problems should not be dismissed. The real danger is not that London will collapse, but that a country convinced its capital is beyond saving will stop trying to understand it. The King’s College study is a reminder that facts still matter, even when they are inconvenient. It is also a reminder that cities are not just statistics. They are places where people fall in love, raise children, face hardship and build futures. To reduce London to a dystopian fantasy is to ignore the lives of the nine million people who call it home. Khan’s words may have been political, but they were also personal. He was defending a city he clearly believes in, and asking the rest of the country to see it more clearly. Whether that will happen is uncertain, but at least the evidence is now on the table. The question is whether anyone is willing to look at it.
