Labour leader Sir Keir Starmer and actor Idris Elba spoke to the families of knife crime victims, as Sir Keir pledged to ban the online sale of zombie knives “straight away” if he becomes prime minister.

Labour has announced a five-step plan to tackle the issue, including guaranteed sanctions for young people carrying knives, and Sir Keir has pledged to chair an annual summit to track progress towards his goal of halving knife crime within a decade.
