I am not sure Jeremy Corbyn is going anywhere.
I am told 13,000 people joined Labour last week, with 60% giving the reason they are "supporting Corbyn".
Apparently many are signing up directly via the button on Momentum's website.
MPs opposing Corbyn, and supposedly "saving Labour", look chronically disorganized in comparison.
They also look parochial.
The phrase "saving Labour" may be self-regarding and unambitious at a time when it is the identity and future of the country which is seen by many to be at stake.
