It pains me to do so, but I congratulate the Mayor of London on the alcohol ban. We supported him in doing that and helped with the necessary byelaws to make it work. The hon. Gentleman will be aware that crime has gone down not just on the railways, but on the tube system as well, largely as a result of the investment in more British Transport police and more police and community support officers on the tube as well. The danger is, of course, that with some parties recommending cuts, that could mean cutting those police and PCSOs, which I think would have the impact of making crime go up again.
