From what I can gather, Jeremy Clarkson has had an affair with his ex-wife, so he took out an injunction banning said ex-wife from talking about their dalliance, which has now been lifted at his request and that of his current wife...

The Sun reports: "The telly presenter, 51, told The Sun he and current missus Frances, also 51, decided to lift the injunction after deciding it was 'pointless'. First wife Alexandra Hall claims their sexual relationship continued after he wed Frances. Clarkson applied for the order - granted last October - to be lifted so he could defend himself against claims. The High Court Queen's Bench Division agreed, meaning Ms Hall can now write about her allegations for the first time. But last night Clarkson - who will spend the rest of the week working 300m under the ocean on a Royal Navy sub - said: 'Injunctions don't work, they are pointless. If you have one, everyone on Twitter and the internet knows you've got it. But because I am bound by the same order, I can't speak about it or defend myself. There is an assumption that I am guilty because I can't say anything. My wife and I decided to let it go. My ex-wife is now free to tell her story and people can either believe it or not, it's up to them. I will be on a nuclear submarine'."

As for the other blonde he was (allegedly) having it away with, she's probably on the submarine too.
