I am absolutely willing to accept responsibility for systemic failures across the whole of policing where they occur. I do not know whether the hon. Lady was in the House at the time, but she will have heard me apologise profoundly for the problems we have seen in rape investigation over the past decade, for example, and put a plan in place to sort that out. Happily, that plan is showing early signs of improvement.
What is really depressing about this exchange is the unwillingness of the Opposition to accept that even a shred of responsibility or accountability should attach to City Hall, notwithstanding the fact that in law and in truth the Mayor of London is the primary accountability mechanism.
