I thank the Home Secretary for her statement about this utterly horrific incident and for the way she made it. In memory of those who have already lost their lives and those who are still suffering in hospital, can we challenge the whole knife culture that exists on the streets of many of our communities and constituencies, where people believe that somehow or other carrying a knife is a good and cool thing to do? Young people have lost their lives. A horrific incident has taken place. People are traumatised by it. That message needs to go to everybody who thinks that carrying a knife is somehow a good or cool thing to do.
