Actress Brooke Kinsella is to launch her report on tackling knife crime on Wednesday, two and a half years after her brother Ben was stabbed to death.
The former EastEnders star – whose 16-year-old sibling was knifed in a north London street in 2008 – is expected to recommend that children are educated at school about the dangers of bladed weapons.
She is also likely to call for more action to combat the problem of girl gangs.
Early intervention must begin at primary school level, while knife crime education should be part of the secondary school curriculum, the report is expected to say.
Home Secretary Theresa May will introduce Ms Kinsella’s report Tackling Knife Crime Together – a review of local anti-knife crime projects.
The actress told the Sunday Times: “There are many, many good kids out there but a small percentage of this generation has got lost in knife culture, and if we don’t want to lose the next generation, starting at 14 or 15 is too late. By then they’re in it and it’s quite hard to change their minds.
“Early intervention is important because it’s when kids go from being king of the castle at primary school to bottom of the food chain at secondary. That’s when they have to start forming groups to protect themselves.”
Ms Kinsella began working with the Tories on knife crime before the general election and spent July and August talking to project leaders and community workers about the issue.
Her brother died on June 29, 2008 after a fight in a bar spilled out on to the streets in Islington. He had been celebrating the end of his GCSEs.
