Why should he be made an example of? What's nice about living in Britain is that our justice system is fair and everyone is equal under the law - even if they think they're not.
So he will get jail time, it will be increased because he didn't admit the original defence and continued to deny it until yesterday and he will have costs awarded against him.
Just like everyone else.
Maybe it's possible that sentencing can take into account his position and the ability he had to turn people to his favour - though I never saw much evidence of that amongst ordinary people. If there is that element, I don't doubt it will be applied too.
I don't think anyone needs it pointing out to them that perverting the course of justice is a serious offence. Though this has taught people that lying about an offence, even a common one like taking speeding points, is perverting the course of justice. I don't think it will stop people doing it but that's up to them.
But if we can make examples of people because we don't like them beyond the crime they've committed and the clearly-defined aggravating circumstances then people like Huhne are going to be in a far better position than the rest of us who have no money and no influence.
