I apologise to Guido for thinking his theory about the injuncted email contrived. It seems that police sources have alleged to the News of the World that Number 10 did leak the email itself, presumably so as to try to engineer a mistrial.
I am no expert on current criminal law, but it seems to me that if true this would, in itself, be another attempt to pervert the course of justice. It could form the basis of a completely separate charge.
The "cash for peerages" story is really now irrelevant. If, as some allege, the Prime Minister's team has destroyed evidence, lied to the police and now deliberately leaked an email to the press to compromise a criminal trial, these are much more serious offences. Conspiracy to pervert the course of justice carries a theoretical maximum sentence of life imprisonment, although 10 years has been the longest sentence to date.
Frankly, if the office of our head of Government had really been involved in such a crime (which I am reluctant to believe) it would be time for the judges to break that record. The culture of "spin" which has grown up around Tony Blair is utterly despicable. There is no question that he and his staff are habitual deceivers.
Let us hope that habit has not been carried over into the world of criminal justice.
