My hon. Friend is entirely correct and that is why I made specific reference to that point earlier in my speech, when I addressed the business planning for the introduction of the card. I referred to the need to be sure that the charge, when finally set, takes account of the circumstances of less well-off citizens. My hon. Friend is right to raise that point and many other colleagues have also raised it. The assurance that I give is that when we come to look at the precise business plan for a charging regime, the particular point that she has made will be taken fully into account.
