Government punished at by-election, more at 10? You have done worse in the past with by-election paper candidates, it tells us nothing we haven't learnt since May 1st, and is nothing compared to Crewe since you faced the by-election squeeze here.
As to the BNP, they got what, less than 4%? Well, I guess we can be glad the greens got 3rd but it doesn't really matter, since Sedgefield & the London assembly it will take more than 3% to get them much media attention. I mean, yes its bad they got it, but losing your deposit is hardly much to talk about, only news at all because everyone hates labour.
