In 2021, Greater London recorded 133 homicides, including a record number of teenage deaths largely driven by knife and gun violence, with Newham emerging as the most affected borough and the data highlighting stark racial, geographic, and socio-economic disparities.

In 2019, Greater London experienced a significant rise in homicides, reaching a 10-year high with 147 recorded cases, predominantly due to an increase in knife and gang-related violence. This marked a worrying 50% hike in homicide rates since 2014.
