The mayor’s team points to falls in knife injuries, homicides and lethal gun discharges since 2016, but opponents and bereaved families say headline percentages mask local spikes, dataset caveats and volatile year‑on‑year changes.
A row has erupted over the Mayor of London’s assertion that knife crime in the capital has fallen, after City Hall reiterated a string of statistics it says demonstrate progress since 2016. A spokesperson for the Mayor of London told the Evening Standard: “Nothing is more important to the Mayor than keeping Londoners safe. Sadiq is determined to do all he can to tackle crime and its complex causes and build on progress that has been achieved in London, with the number of young people being injured with a knife down 26 per cent, homicides down 17 per cent, gun crime with lethal barrel discharges down 43 per cent and burglary down 27 per cent since 2016.” The intervention has prompted criticism from opposition politicians and some bereaved families who dispute the mayor’s framing.
City Hall has repeatedly pointed to falls across a range of offences in material accompanying its announcements, but the exact figures depend on the comparative window and dataset cited. In separate City Hall releases the percentages vary: one press statement highlights reductions in homicides, lethal gun discharges and burglary; a separate City Hall briefing on mentoring investment set out slightly different declines for knife injuries among under‑25s and for homicides. City Hall attributes the improvements to joint work between the Metropolitan Police, the Violence Reduction Unit and local partners and to sustained investment in both policing and early intervention. It has also announced stepped‑up beat policing in town centres as part of that response.
Independent national statistics offer a broader context but also urge caution. Office for National Statistics data for the year ending March 2024 recorded 570 homicide victims in England and Wales, a 3 per cent fall on the prior year and the lowest tally since 2016 when pandemic years are excluded. The ONS analysis notes that sharp instruments remain the most common weapon and that teenagers are disproportionately affected, while also warning that small‑number year‑on‑year changes can be volatile and should be interpreted carefully.
The picture for gun crime is similarly mixed. The Metropolitan Police has reported substantial firearms recoveries — roughly one firearm seized per day in London in the most recent year — and BBC reporting shows there has been a fall in lethal barrel discharges since March 2023, from 196 to 145 incidents. At the same time, other recorded gun offences increased between 2022 and 2023, underscoring the complexity of trends in armed offending and the concentrated nature of much gun and gang violence.
Critics say headline percentages risk obscuring local and demographic variation, and families of victims have told the Evening Standard that the capital remains dangerous in certain communities. Researchers and policymakers also point to limitations in homicide datasets: the Metropolitan Police’s homicide dashboard — published to improve transparency — includes methodological notes and jurisdictional caveats, and some London killings fall under other forces such as the City of London or British Transport Police. These qualifications, along with the ONS’s warnings about small‑number volatility, are commonly invoked by analysts who urge caution about broad national or city‑wide claims.
That debate frames the policy argument City Hall is making: prevention and policing together. City Hall’s recent announcements highlight the Violence Reduction Unit, record mentoring investment aimed at more than 100,000 young Londoners and promises of extra officers in high‑impact town‑centre patrols. The mayoral team says these measures, alongside policing activity, are essential to sustain and deepen reductions; opponents say more must be done and that statistics alone are not a substitute for local safety improvements. With data showing both falls in some serious offences and rises or concentration in others, officials and community leaders agree the task remains to translate headline numbers into safer streets for the neighbourhoods still most affected.
