However the wheels are starting to fall off.
Over the last two days his bogus claims that he'd been invited by the UK Parliament to speak there have been exposed as deliberate misrepresentations aka lies. Even the UK Parliament's press office weighed in and said that an invitation to a reception "should not be taken as an invitation to address Parliament as a whole".
Even his talk at University College London on Sunday evening ran into problems with the organisers initially cancelling his appearance before Abhisit and Korn's team apparently pleaded throughout the early hours of Sunday morning begging for him to be allowed to talk.

Finally he is interviewed by the BBC and finds himself confronted with someone who is not going to just let him put out his lies and follows up with some quite decent questions (if only for 5 similar foreign journalists in Bangkok). In this interview he utters a line that will complete Abhisit's enduring and well-deserved infamy - "Unfortunately Some People Died"
It's pretty much a car-wreck of an interview for Abhisit and on several occasions his false smile slips as he attempts to talk-over the interviewer and squirms in his seat.
