The "Please go" petition on the No 10 website is now past 64,000 signatures. After a period of slower growth in the last two weeks (presumably due to the distraction of the expenses scandal) it seems to have gone back to growing much more quickly.
I think this is because people are starting to realise across the country that Gordon Brown has to go now. The man is deluding himself if he thinks he can recover from this. He is supposed to be battling the recession but I suspect much of his energies are being put into desperately trying to consolidate his own position. this cannot go on.
