Thanks to Stu_N for the direction, but Charlie Brooker's piece on Boris Johnson and the London Mayoral election is a classic.
I'd probably back off from saying that BJ is a dim waste of space (he was an enthusiastic and reasonably informative guide on classical history etc) but as CB's header says "I wouldn't trust Boris to operate a mop, let alone a £10bn Crossrail project."
If you're a London voter I'd advise:
1) VOTE - don't waste it
2) UT please, we beg you PLEASE, do NOT vote for Johnson
