I, like Dave, have been a long term supporter of Nige, and although joy is particularly thin on the ground at the moment, I'm not quite ready yet to join the "Pearson out" lobby.
As to an admission of being wrong, well I'm quite comfortable with that as I'm certain Dave is.
It seems to me that the rather more childish posters on here are often keen to get some sort of apology from anyone, for anything, as being right is being clever, and therefore helps to reinforce a fragile ego.
Let them eat cake I say Dave, no need for you to step down.
