‘The two-year time-limit in Article 50 of the Treaty on European Union has come and gone. It is now possible that no withdrawal agreement between the European Council and the UK will be concluded. This means that the UK would leave the EU in catastrophic circumstances on April 12. An interesting final irony would be that the UK would be leaving the EU on the basis of a legal howler.’
