Boris won’t be forgiven if his No. 10 chaos makes him cave on Brexit

Mayhem has once again engulfed 10 Downing Street with the dramatic resignation of Lee Cain, Boris Johnson’s communications chief. He was with the Prime Minister on the Vote Leave campaign — as had Dominic Cummings, Oliver Lewis and others who have formed a band of brothers in No. 10. Cain’s departure put a question mark over the future of the others, which comes at an odd time because the Brexit they all campaigned for is weeks away from a conclusion.

There are huge issues facing the government: a second lockdown, due to end on 2 December. The procurement and rollout of a potential vaccine. But another deadline, just weeks away, is Brexit. This is the mission Johnson was elected to accomplish, this is the drama that has defined British politics for the past five years. We are weeks away from a denouement. The architects of Johnson’s Brexit strategy seem to be at war with others in No10 – and, meanwhile, the chances of a deal are 50/50.
