If our criminal justice system works at all, then the slimey Andy Coulson will soon be behind bars for conspiracy to pervert the course of justice. The Guardian has just published a whole raft of evidence released by the select committee, of which this is not the only bit which seems to have Coulson – the “editor” in question – absolutely bang to rights.

Of course, while the justice system can work 24 hours on convicting people who nicked some maltesers, Scotland Yard have still proved completely incapable of identifying any of the policemen who took Murdoch’s bungs, or in locking up Coulson and the other News International executives who are guilty as sin.

Given this letter from Goodman making plain that Coulson instigated a cover-up of the extent of culpability within N.I., it seems that Cameron must resign for having brought a definite criminal into the heart of 10 Downing Street, despite numerous warnings. Cameron is compromised by this beyond repair.
