I think you'll find this one case quite true, Private Eye has done several pieces on it.
It would only be true if the individual in question had managed to secure an exemption to the law specific to him. Given that all legislation is published in this country, and no such exemption exists, we can conclude it is made up fairy stories. If you can show me the piece of legislation which implements said exemption I might be willing to take it seriously.
Quoting (or implicating) Private Eye, a publication famous mainly for publishing falsehoods and then having to beg the readership for money to defend the libel claims, is not in itself any sort of proof.
