Labour go ahead in the polls (and Tories slip at local level)

In the first poll as Labour leader, Ed Miliband has pulled the party ahead of the Tories for the first time since the election that never was in 2007.

Meanwhile, local by-election results over the last few months are pointing to an 11% drop in the share of the vote for the Tory party, which, if continued, would see the party lose numerous seats to Labour in next year's local elections (and may see the latter gain full control of the Welsh Assembly).
