YouGov poll of Londoners
Today's Evening Standard carries a new YouGov poll of London. The topline voting intention figures are CON 45%, LAB 33%, LDEM 16%.
This represents a swing of 9.5% from the last general election, which is actually marginally lower than the swing to the Conservatives in the country as a whole, which the last YouGov poll suggested was 10.5%. The giant PoliticsHome poll of marginal seats last year also suggested that London was one of the Conservatives weaker areas.
I can't see any other questions in the Standard's report, but in the past they've tended to commission polls and then report results over a couple of days, so there may yet be more.
