After the shock of the referendum result, Remain MPs have regrouped. The All-Party Parliamentary Group on EU Relations, founded by Umunna in July and co-chaired by Soubry, is the main vehicle for their activities. Amendments to the government’s EU Withdrawal Bill have been meticulously co-ordinated to ensure maximum impact (the MPs use a WhatsApp group and often meet in Umunna’s office).

Remainers boast the media savvy of Umunna, the lawyerly expertise of Dominic Grieve (a former attorney general), the economic nous of Nicky Morgan (the Treasury select committee chair) and the rhetorical firepower of Soubry. Though most state that they are merely opposed to “hard Brexit” (defined as UK withdrawal from the EU single market and the customs union), they are alive to the possibility of halting Brexit altogether.

Beyond Westminster, some of Britain’s most senior politicians have opened back channels to Brussels. On 30 October, to the consternation of Brexiteers, Michel Barnier, the EU’s chief negotiator, met Nick Clegg, the former Labour cabinet minister Andrew Adonis and the veteran Tory backbencher Ken Clarke. During their Brussels meeting, Clegg impressed upon Barnier how “extraordinarily fragile and febrile” British politics was. Barnier, who had met with Jeremy Corbyn for 80 minutes earlier in the month, is mindful that the Conservative government could collapse. Out of chaos, the EU hopes, order may yet emerge. “What was clear from my meetings in Brussels is that they desperately want us to stay,” Adonis told me. “I didn’t meet a single person who thought that the EU would be better off without us.”
