A charity is calling for all primary school children to be taught how to avoid getting involved in knife crime as part of the national curriculum.
Maya Joseph-Hussain, who is chief executive at the Safety Centre in Milton Keynes, said "every young child should have access to this education".
Knife crime prevention is discussed in schools but is not mandatory.
The government says it is reviewing how the issue is taught as part of a wider review into relationships, sex and health education (RSHE).
