I know - it's a week late. But I picked up a snippet the other day that tells you why Labour lost in Glasgow East...

Apparently voter contact had been absolutely zero for years. David Marshall had done virtually nothing for years (apart from perhaps collecting money from us for his carefully chosen constituency staff). He supposedly didn't even venture into the constituency much and held few if any surgeries. When they started the by-election campaign they were starting voter identification from scratch with no reliable previous data at all.

Utter bonkers. They absolutely deserve to have lost with the level of contempt towards the constituents that smug inactivity over the years demonstrates.

On the other hand, it puts the SNP victory in some context - were they any better than, say, the IWCA in Oxford whose only reason for existing as a force on the council was Labour's contemptuous attitude in their "safest" wards.

UPDATE: And I see from Dan Paskins that there is a motion in to conference saying much the same .
