Guido has long believed that Lord Levy and others would face trial. That opinion was until recently very much a minority opinion, as late as this spring Nick Robinson and Michael White were telling us that the police would only go through the motions and nothing would come of it. Only two months ago the Observer told us that the investigation was over and the CPS had found nothing. A fortnight ago Nigel Griffiths, deputy-leader of the House of Commons said he “understood“ that the CPS had found no evidence and it was all over. It ain’t over yet.

Labour sources have gone from believing “it will all blow over” to an unspoken group-think that they would spin their way out of it, to now hoping they can quash the CPS. There is a realisation that this is now the last chance to stop charges.

You can’t spin a detective easily, every criminal claims he is innocent, but coppers, unlike some of our finest political journalists, work on the assumption that their interviewee is a lying wrong ‘un.

The CPS is Downing Street’s last hope. Nigel Griffith’s bit of wishful thinking spoken aloud on air was the premature hope of the guilty party. To the frustration of the attorney general, the police have not given the CPS much of substance yet because they don’t trust the political independence of the CPS. They will give the CPS the full goods only when the investigation is complete and they are sure that they “will be taking the case to the Old Bailey“. Be assured that is the intention of the police.

Don’t pay any attention to the spin from New Labour – they are shitting themselves. “The Fix” is falling apart. Inside the CPS they are not happy at it being taken for granted that they will be a patsy for Downing Street.

Look at the arse-covering manoeuvres going on in certain quarters – a sure sign that those in the know, know “The Fix” is not in. Sir Ian Blair, our most politicised policeman has taken himself out of the decision making – citing his relationship with the PM. Ken MacDonald, the Director of Public Prosecutions, has done the same. The CPS has turned outside its own ranks to David Perry QC to advise. That leaves only the attorney general, Lord Goldsmith, batting for Blair. It is up to the political classes to see to it that he is prevented from quashing charges or just plain interfering. This discredited lawyer (his flip-flop advice over the legal basis for Iraq was made at Blair’s bidding) should not be permitted to block the course of justice. Shadow Home Secretary David Davis and the Shadow Attorney General Dominic Grieve have Goldsmith in their sights.

Downing Street is not going to be allowed to whitewash this…
