I’m a little late with this, but just to flag up that yesterday’s Times had a new YouGov poll of London. Topline voting intentions there are CON 34%, LAB 42%, LDEM 8%, UKIP 9%, GRN 6% (tabs here).
I sometimes hear a sort of London as the weathervane of the country argument, as London goes so the country goes. It doesn’t, despite a Tory mayor it’s Labour leaning compared to the country as whole, and it doesn’t necessarily swing in the same way as the rest of the country either. In 2010 while the Conservatives were seven points ahead in the country as a whole, Labour won in London by 2 points, and the Conservatives managed a smaller swing in London than elsewhere.
This poll suggests a 3 point swing from Con to Lab in London, the equivalent of a 1 point Conservative lead in national polling, so actually a little less than national polls are currently showing. It could be the Tories are doing a little better in London, or it could just be ordinary sample error – as ever, it’s just one poll and shouldn’t be overinterpreted. A three point swing in London would net Labour three or four gains from the Tories – Hendon, Brentford and Isleworth, Enfield North and, right on a knife edge, Croydon Central.
