Make no mistake, this is a much more bold challenge than Hazel Blears, who didn't mention Brown in her resignation statement. Purnell has said the following:
I don't see how Brown can survive much longer. We'll see the local election results tomorrow... but does anyone believe they won't be dire?
"I now believe your continued leadership makes a Conservative victory more, not less likely. That would be disastrous for our country.... I am therefore calling on you to stand aside to give our party a fighting chance of winning. As such I am resigning from government."
