I'll do the graphics in the morning (rushing off to dinner with John O'Sullivan) but there's an ICM poll for tomorrow's Guardian giving the Tories a 9% lead. The Tory advantage is 40% (+3%) to 31% (unchanged) over a Blair-led Labour party with the LibDems on 19%. The lead grows to 42% to 29% with Brown in charge. The LibDems would drop to 17%.
