Well her version was that he had already, without her agreement, nominated her as the driver. He then presented her with the form to sign.
So her choice was to sign or destroy his career, because he had already lied.
Her mistake was going to the press, rather than the police. If she had gone to the police and admitted what had happened from the off, she would have received a caution and his career would have been finished in any case.
But I do think the Judge's remarks were incredibly misogynist. I don't think a man would ever have been called "devious and manipulative". He talks about CH's guilty plea, having lied for two years, as requiring "courage".
Says it all, really.
