Why the change in Boris and Ken prices?

There’s been a sharp move to Boris during the past hour in the London Mayoral race betting. As at 12.25pm he was at 1.51 which he was last at before the Unison-sponsored Ipsos-MORI poll in Wednesday morning.

A couple of people have emailed me to say that the Observer is carrying a poll tomorrow and the paper’s normal pollster is Ipsos-MORI.

I don’t know the truth of this but have been following the markets closely.
