1) Keep the message simple
"We cannot trust Johnson. He's talking about breaking the law. Whatever date we agreed for the election he would just move it till after the 31st October, and we crash out, no deal, in the middle of an election. He cannot be trusted"
"This isnt about a GE. Johnson doesn't care about a GE in the same way he doesn't want a 2nd Ref. But his ERG masters desperately want a no deal #Brexit and they'll shut down parliament, break the law or even throw a GE as a scheme to get it"
Please, gloves off, be assertive, land the messages
Johnson is calling a GE as a trick, because Cummings painted him into a corner
He's degrading the process of a GE for his own obsession
And start asking "*Why* is Johnson so obsessed with getting no deal? Why is he doing all he can to sneak in a no deal by the back door?"
Passion, FFS!
