When the Guardian even admits Brown lost you know he's had a bad night.
What do you mean by "when the Guardian even admits Brown lost" ?
The Guardian isn't 'the Labour Party'. In fact the Guardian hasn't even decided who it's going to support this election :
Election editorial: who should the Guardian support?
You'll notice in that article, that out of the 17 general elections since 1945, the Guardian has supported the Liberals, Liberal/SDP Alliance, or the Liberal Democrats, 13 times.
The Guardian has only given the Labour Party unequivocal support three times since 1945.
And in fact even in 1945 when the Labour Party achieved a landslide victory and was, unbelievably, supported by the Times, the Guardian supported the Liberals.
The Guardian has always been an untrustworthy liberal bourgeois paper.
