Profit - seems to be the driving force behind most decisions made.
Ummm, £8m loss last year; £8m loss forecast for this year too. Making a profit is so far from reality, it's laughable. TB and PB have both said that any cost savings/extra revenue generated will simply be ploughed in to the playing budget, keeping the loss at the maximum allowed by FFP.
It could be argued that stocking the book would generate extra revenue, thus allowing more to be spent on the paying budget while keeping the overall loss to £8m. I would imagine that the total marginal income (after the wholesale cost of the book) would be under £10k, which doesn't go far these days in a playing budget. If there are unpalatable things said in the book, it would be a perfectly reasonable decision to not stock it. If they haven't seen it yet, it's also reasonable to defer a decision until they have seen it.
I do agree with Bozza's assertion that it is sad if TB and DK have fallen out. Sad, but not unexpected - "The King is dead; long live the King" is a lot easier to deal with than "The King is deposed; long live the King". There will always be resentment from the old King and his followers towards the new King, especially if the old King still has a role that keeps him around (such as life presidency).
