This month's Ipsos-MORI figures have been released and Labour appears to have eaten a hefty chunk out of the Tory lead:
Conservatives --- 42 percent (down 6 percentage points)
Either way, I think Downing Street will be more pleased than not with this. Throw in the YouGov poll from the weekend (which had also had a reduced gap of 10 points between the Tories and Labour), and there's some evidence of a small post-Obama bounce for Brown. Yet, it must be said, the medium-term fundamentals remain dead set against him.
P.S. Guido highlights a striking gap between the party's leader's personal ratings: 59 percent are dissatisfied with Brown's performance as PM, while 52 percent are satisfied with Cameron's performance as Tory leader.
