I think there are two principal reasons.
One is that we believe very strongly that all the relevant information has already been published, and the way we do it helps to deal with that risk, as I said earlier, of accidentally giving away personal information. The information commissioner disagreed with us and it was almost for things like, what's the colour of the heading, or did the MP scribble something on it? It's that kind of thing. It becomes quite an arcane argument about what constitutes information. I won't bore you with that now but that is the sort of legal issue.
The other issue, which in many ways is just as important, is that this will be an incredibly costly exercise. It would cost at least a million pounds a year to have the redaction team that is necessary to take out all the personal information. We also have a backlog. We've got about 600,000 to 700,000 receipts now, and if we have to publish all of those, that would cost us, again, almost a million pounds. It would be a massive undertaking with very little public value.
