Mr. Stephen Mulvany:

The trolley numbers did not hit their peak on 22 December. We acted before they hit their peak because the prospective data were telling us we were not getting a clear-out. Everything pointed to the idea that there was going to be a very high trolley number in the days after Christmas. It was not that it was visible at that point; we were facing a slowdown or a reduction in trolley counts at that stage, but it was nowhere near what might be expected at that time of year. All of that added together suggested this was going to be even worse than our worst predictions, and that is why I called for the national crisis management team.
