Bloody hell London - do the right thing and vote for Ken Livingstone for Mayor.

Boris - for and against.

Boris is such an unknown quantity - is he a racist snob, as some say, or could he genuinely do a good, non-political, able and inclusive job for London in a position that anyway does not wield that much power, as others say? Neither he nor Ken is a party lackey.

In the end - beyond floppy foppishness, photos on bikes or on the Tube, charisma and broken marriages - we're talking about a city. It takes a really long time to get anything done. Right now the city has momentum - Crossrail, the Olympics, congestion charging, integrating the various transport networks. I'm unwilling for that momentum to be halted. Bring Boris into the fold - after 4 years we'll know a bit more about what he's made of. Ken will have to leave at some point anyway.

So, even giving Boris the benefit of the doubt - i.e. that he is not a racist fop with an attention span that makes a Coca Cola-drinking kid with ADHD look like a Confucian scholar - I'd vote Ken out of caution, as a safe air of hands.

Unfortunately I'm in Beijing, so I'm relying on everyone else. Don't stuff it up - vote Ken.
