I'd claim it, but no one would believe me

A busy weekend for Belle de Jour denial everywhere - Sarah Champion now categorically denies it in The Observer as Rowan Pelling denies it in the Independent (but you have to pay to read her declaring she's not a prostitute, which is kind of ironic).

But I have a theory - Belle de Jour is a actually a real call-girl, who puts on a psedunymous, anonymous disguise to write British Spin.
