The London based press seem mildly annoyed that Andy Coulson had to endure being driven to Glasgow in a people carrier with seven policemen for company. Why didn't they fly the poor soul there - it is a long way, is the plaintiff cry.

Maybe because alleged perjurers do not and should not get special treatment.

The emphasis in reporting, at the moment, once more seems to focus on phone hacking - but this time that emphasis is misplaced and the real focus may be on his conflicting evidence given in two different depositions about paying-off police officers.

Andy Coulson, during the perjury trial of former Scottish MP Tommy Sheridan, said: “I don’t accept there was a culture of phone hacking at the News of the World.”

He also denied knowing that the newspaper paid corrupt police officers for tip-offs.

However in a joint evidentiary session with Rebekah Brooks at the Parliamentary Committee, Ms Brooks stated clearly that NotW had paid police officers, just before Mr Coulson cut her off by adding that News International only paid-off police officers by legitimate means, to which Ms Brooks vigorously nodded her assent.

Unfortunately for Mr Coulson it has subsequently emerged that there is no legitimate means whereby any payment to policemen for such services can be made. It was just Mr Coulson's and Ms Brook's short term good-luck on the day of their evidence to Parliament that no committee member new that this statement made to the Committee was a confession of illegal activities to which both persons could be deemed to be allegedly culpable.

For Mr Coulson however, his evidence given to Parliament and his evidence made in the High Court in Glasgow provides potential evidence of alleged perjury on his part on at least one of those occasions. It simply cannot be the case that both of his statements could be true at the same time, hence the close examination of his alleged perjury.
