Of course there is a case against Tony Blair.
That is precisely why he is not going to stand trial.
They cannot risk a conviction, although of course there are ways of ensuring that that did not occur.
But nor can they risk an acquittal, since of course that would destroy all public confidence in the judicial system forever.
So, of course, there is not going to be a trial at all.
Meanwhile, of course there is no case against me.
That is precisely why, at the time of writing, I am going to stand trial, to prove that I can still be convicted even if no case whatever is even attempted to be made against me.
While the action against me continues, that is a matter of public record.
