We certainly would not be held responsible for those I would hope! Just talking about what happened at the press conference, we have discussed this with Tim O'Toole and he says that you went to the press conference basically unbriefed about this issue which appeared on the front page of The Sun newspaper that morning.
If it had been another type of issue, if there had been an incident or if there had been a policy announcement I assume London Underground would have briefed you before the press conference. I would have thought that it was almost a no-brainer that the press were going to ask you about that.
Have you reconsidered briefing arrangements with London Underground so that they can pick these things up in future? There is clearly an error here.
