You talk about the will of the party, and of party members, quite regularly. It should be noted that this isn't a stable bunch of people who have been with Labour through thick and thin, but is a group which includes a huge number of new "£3 members" at least some of whom don't have Labour's interests as a top priority. As much as their is a Blairite (or moderate) faction who may be plotting against Corbyn, there is also a group of Corbyn supporters called
Momentum who have, for instance, threatened sitting MPs, and have an agenda including the restoration of the ridiculous Clause 4 of the LP constitution. It is the Militant Tendency of the current era, and is apparently actively encouraged by Corbyn, even though many of its members have agendas not primarily focused on the health of the Labour party. So, "nest of vipers" doesn't apply just to the PLP.
