I think VP was pressured, but not coerced. There is a world of difference between the two. As I understand it, to make out the defence you've effectively got to show the spouse stood over you and made you do it. That wasn't this case.
Her own evidence showed that: yes I stood up to him over the second abortion, but no I couldn't years later with a v good job, older children and more independence when he demanded I take his speeding points. Not credible.
And let us not forget she didn't dob CH in to the cops, she took her story to the media. The original version had an entirely blameless young Lib Dem activist taking the points for CH. That story fell apart because the journos established the young woman didn't even have a licence at the time. But if she had, she could have been investigated and caused all kinds of problems, just so VP could have her revenge. That is an absolutely appalling act of casual dishonesty that has been overlooked.
Along with being prepared to disclose to her son that his father wanted him to be aborted, it is hard to feel anything other than distaste for VP. However bad you think she is, though, Chris Huhne is a thousand times worse. Let the costs order be swingeing.
