Ever since the News of the World broke the story at the weekend that Mark Oaten, former Liberal Democrat Home Affairs Spokesman, enjoyed the company of young male prostitutes, I have been mulling over the phrase "humiliate him with a bizarre sex act too revolting to describe".
I have today been passed information from my man in Westminster that would indicate that Mr Oaten's preferred way of being humiliated was to have rent-boys defecate on his chest or to urinate on him, whilst he proceeded with getting his rocks off.
Whether this is in fact what happened I doubt we'll ever find out, but it certainly ranks up there in the too revolting to describe (except on seedy second rate websites) category.
What is interesting is that rumours have also been surfacing recently about fellow Lib Dem MP and total heterosexual [1], Simon Hughes, who was alleged to have paid a prostitute to deposit little brown fishies in her knickers, which he then carried round in his briefcase. This sounds too bizarre to be true, but then we all know the fate of Stephen Milligan MP, who died in February 1994 after a bizarre sex act that went horribly wrong. He of course died of asphyxiation after strangling himself with an electric flex, whislt wearing stocking, suspenders and a black bin-liner over his head, complete with an orange in his mouth. A tragic case of auto-erotic sex gone horribly wrong.
Anyway, back to the point, it looks like that only leaves Menzies Campbell in the running, unless you count that new boy that no one knows the name of. You too will be able to order your commemorative "Ming Vases" from the Franklin Mint shortly after his coronation as Lib Dem leader.
[1] Simon Hughes of course hired black teenage male research assistants purely for assisting him with the process of dealing with parliamentary work, and any insinuation of sexual activity between them is absolutely false.

As usual you are right on the money:

I like the fact that he is now using his sexual preferences as a shield. It's the fall of the Roman Empire I tell you!
Are we talking about the Simon Hugues of the 1983 by-election fame who won with the anti-gay slogan: "Simon Hughes - the Straight Choice"?
Oh, the Irony!
