They're very relevant, given that this is precisely what the article you are linking to is talking about. I don't want to defend Chris Huhne particularly, because he's guilty of a whole lot of stuff I take a dim view of. But he's not quite guilty, yet, of blaming the media, or anyone else, for forcing Vicky Pryce to take his speeding points. Except, possibly, blaming Vicky Pryce herself.
As it happens I don't think it matters much if there was an agenda behind revealing the story of his crimes, because they should have been dealt with some time ago and to some extent he was lucky to have evaded justice for as long as he did.
