YouGov's first post Hoon-Hewitt poll
Here's the effect of Labour's leadership infighting: Sky are reporting that the Sun has fresh figures from YouGov in tomorrow's paper and show a shift back towards the Conservatives. The topline figures with changes from yesterday's poll prior to Geoff Hoon and Patricia Hewitt's attempted coup are CON 42%(+2) LAB 30%(-1) LDEM 16%(-1).
The changes themselves are within the margin of error, and furthermore conducted when Labour's infighting was splashed all over the TV and newspapers, but nevertheless I expect it will be taken as a salient reminder of the damage that party infighting can do to support.
I'll update later when the Sun story comes out and we see what other questions there were.
UPDATE: The exact timings of the poll are between 4pm yesterday and noon today. Sample size was 2,832.
