Christopher Monckton , Lord Crazypants of Brenchley, made a fool of himself today at COP18 in Doha, Qatar by impersonating a delegate in a plenary session. He was immediately debadged and escorted out of the conference, and is likely being deported from Qatar right now.
The UN now confirms that Lord Monckton has been permanently barred from the UNFCCC process.
Cindy Baxter broke the news on Twitter :
Good riddance, indeed. Over the years, Monckton has attempted to disrupt the UN process with various stunts  of ill-taste - but none so offensive as the one he tried to pull this time.
