The Minister is absolutely right about public sector workers. I mentioned that the Royal Marsden Hospital is having to refund ULEZ charges to cancer patients. One other point we must surely consider is that something like half of all Metropolitan police officers live outside the geographical area of Greater London. No wonder people do not feel that they can come and work in the city if they have to pay £12.50 a day. Does the Minister agree that ULEZ will surely have an adverse effect on crime in London if the majority of our officers have to travel in and pay £12.50 a day to police our streets?
