A final thing that has hardened attitudes is what happened to shadow ministers when they returned to their offices after Tuesday’s shadow cabinet meeting. Jeremy Corbyn had asked them to spend time in their constituencies “consulting” with their members. But as they walked into their offices they were informed their parliamentary email accounts had started filling up with demands they oppose military action. The wording on the emails was almost identical, and closely echoed the words used by the Corbynite campaign group “Momentum” in its communication to its own members. It subsequently emerged the wording was being circulated by Simeon Andrews, a close ally of the shadow chancellor, John McDonnell.
