A Crown Prosecution Service source has accused the Government of leaking against itself in the recent "cash for peerages" development. Whilst some may question the validity of an anonymous quote to the Screws, Guido offered an analysis last night which makes it the most logical source of the leak, even if it is the most improbable.
As the BBC doesn't pay for stories, whoever leaked it to them must have had a motive to do so. It wouldn't be the Met as they wouldn't ruin they're own investigation by leaking information that would be prejudicial to their own case.
We know that it was the Police that requested the injunction that the Attorney General placed on the email. It would be an odd state of affairs if the Police leaked an email for free then arranged an injunction to have have suppressed.
I guess there will be some out there who are utterly convinced that there has never been any wrongdoing and that the Police are just causing trouble because they have nothing. I've seen that line peddled by a few commentators who are in Downing Street's pocket before. It wasn't believable the first time round either.
If the Police didn't leak it then that leaves only one other source, Downing Street, where the email was originally found. IT would, as Guido pointed out, serves their purpose brilliantly if they leak against themselves. If they can get the Smoking Gun into the media then the CPS will say they - whoever it may implicate - cannot possibly have a fair trial.
