Wild spending on Brexit preparations makes good political theatre, but it won’t protect us from the impact of no deal. / The civil servant works in a Whitehall department and is part of Operation Yellowhammer.

If Brexiteers had been more honest, arguing we face perhaps a decade of pain to reset our global stance, I would have more respect for them.

Magical thinking on a no-deal Brexit doesn’t change the facts for officials like me who are charged with making it happen.

Operation Yellowhammer from the inside? It’s like the Office meets the Poseidon Adventure, with a Benny Hill soundtrack.
