I wandered past Clapham Junction today to find blonde bombshell Boris Johnson doing some last minute campaigning outside the station. He was on boisterous form and was trying to swing undecided voters by offering short piggy back rides (just to Woolworths and back) in exchange for a vote for him as London Mayor.

Most of the takers seemed pleased with their ride and Boris's stamina was certainly impressive but a couple of times he got caught out by people more interested in a Boris rodeo — they would promise their vote, jump on his back, and then openly admit they were actually staunch Ken supporters and see how long they could stay on.

No-one managed to last more than 30 seconds and at one point things looked like they could get rather nasty when one young man was thrown clean off and into the flower stall and Conservative party supporters were forced to distract a wild-eyed Boris by striking him with rolled up copies of the London Paper to stop him goring his would-be jockey.

Boris seemed to calm down after a stern talk and a Frappucino in Costa Coffee with his campaign manager and, sensing the fun was over, I left them all to it.
