"I am just quite baffled when you have got something as serious as this. When you have got a 70% increase in knife crime in the last 4 years, when you have got a 93% increase in the number of children attending A&E who have been stabbed in the last 6 years, when you have got a 37% increase in homicide, I'm just baffled that you don't have a basic assessment of the number of young people who are at risk - and then have an assessment of what your policies are doing to help young people."
