The seven days of Brexit: how a Leave government could bypass Article 50

Most agree that leaving the EU would entail a negotiating period of at least two years, as set out in Article 50 of the Treaty on European Union. But, argue Frank Vibert and Gunnar Beck, this is not a certainty. If a Brexit vote – combined with a Commons majority in favour of Leave – were deemed to constitute ‘a fundamental change of circumstances’ under the UN’s Vienna convention on the Law of Treaties, Britain could leave the EU immediately. They set out a timetable that would see Britain leave the EU within a week.
