My hon. Friend raises a very important point. If we look at the extent to which knife crime is gang and drug-related, many people across our society need to ask themselves what they are doing to ensure we deal with knife crime and not see drug-related gangs committing these crimes, so that we are able to rid our society of what I believe to be the curse of drugs. I believe they have those impacts. They are bad, and that is why it is important that, as a Government, we have a very clear drugs strategy to take people off drugs and ensure we deal with this issue. My hon. Friend makes a very important point: it is a matter not just for Government or police, but for all of us across our society to deal with these issues.
