Knife crime in England and Wales hit a record high in 2019, up by 7% on the previous year. In the 12 months to June, there were 235 knife murders and 412 attempted murders. A disproportionate number of victims – and perpetrators – are young and disadvantaged. It is destroying lives and striking fear into many communities.

In this episode of the award-winning LSE IQ podcast, Joanna Bale asks: ‘How do we stop knife crime?’ She talks to LSE’s Kerris Cooper, Janet Foster, Tom Kirchmaier and Carmen Villa-Llera. Joining them is Yvonne Lawson, who set up a charitable foundation to work with children at risk in memory of her son Godwin who was stabbed to death in North London.
