Britain is now being held hostage to Mrs May’s vanity. The departure date, we must believe, is the work of divine providence. The prime minister has been heard say it is her “sacred duty” to meet the deadline. Kamikaze Brexiters, who want to see the country crash out of the union, agree. The schedule set out by Article 50 of the Lisbon treaty, they intone, is also inscribed in British law. The country cannot change its mind.

The damage is piling up. Brexit was always going to weaken the economy. A decision to throw up protectionist barriers to trade and investment with Britain’s most important markets could do nothing else. Mrs May’s determination to run down the clock, leaving open the possibility of Britain tumbling out without succour or safety net, has multiplied the costs and dangers.
