Gardiner and Starmer do NOT get on, reportedly - no surprise
Starmer's campaign going very well so far:
Lewis Goodall@lewisgoodall
Big victory for Keir Starmer, securing the backing of Unison, which backed Corbyn in 2015 and 16.
Unison, as one of the biggest unions, gets Starmer closer to being assured of a place on the ballot paper.
Needs two more affiliated organisations, one of which must be a union.
This looks a certainty.
NEW: Starmer's campaign to be chaired by @JennyChapman, fmr MP for Darlington who lost her seat in GE19.
Smart signal about recovering lost ground.
Also coup to get Simon Fletcher as head of strategy.
Campaign director for Corbyn in 15. Smart signal to the left.
