YouGov show Boris ahead in London

A new YouGov London poll has been released here. Westminster voting intention in London, with changes from March, stand at CON 32%(+1), LAB 51%(+3), LDEM 8%(-1), a slightly bigger swing to Labour than the general GB polls are showing.

However, in the Mayoral race Boris continues to lead, with 48% to Ken's 41%. The diference is because Liberal Democrat voters break in favour of Boris, and about a fifth of Labour's Westminster voters would vote for Boris in the mayoral elections.

The figures probably flatter the amount of the vote that both Boris and Ken would get given that other candidates remain unannounced, but it does appears that Boris is maintaining a lead independent of his party.
