Boris's lead grows to 13 points

Politicshome, which officially launches today, has up as Breaking news that the lastest poll (presumably YouGov for the Evening Standard) has Boris Johnson leading Ken Livingstone by 13 points. I'll post properly once I've seen the poll.

UPDATE: The new YouGov poll for the Evening Standard has topline figures - with changes from last week's poll - of JOHNSON 49%(+2), Livingstone 36%(-1), Paddick 10%(nc). Boris Johnson remains slightly shy of an overall majority, so taking into account second preference votes the figures become Johnson 56%, Livingstone 44% - so it appears this time the second preferences are breaking slightly in favour of Livingstone.

Following the fuss last week there is a slight difference in YouGov's methodology to take into account ethnicity. YouGov are now weighting to 26% non-white Londoners. This is somewhat lower than the 29% ICM are aiming for. YouGov's figures are based on the proportion of ethnic minorities over the age of 18 in the 2001 census. 29% is the proportion of ethnic minorities in London as a whole, since the non-white population is disproportionately young. I think it is also - by co-incidence - the GLA's 2008 projection of the proportion of ethnic minorities of economically active age, which I guess is where ICM's figure came from. Whoever is right, the slight difference between YouGov and ICM's proportions of ethnic minorities is not going to make a hugely significant difference, perhaps a percentage point or two.
