At first splash this looks good news for Smith and a setback for Corbyn. But when you look at the figures it is almost at the level of a stunt. There are some 641000 members of this Union. Just short of 44000 took part in the ballot. That is less than 7% of the membership. Of this tiny sample 60% backed Smith. That is 26400 or 4% of the total membership. I am not sure if this can be called an endorsement, but if it can, it is certainly not a ringing one.
