On June 23, the British people decided to leave the EU. I am sorry they did because I believe the UK belongs in Europe. But I respect their choice. I can think of nothing worse than suggesting their decision might be disregarded.
The approaching political talks will be tough and the associated technicalities complex. Article 50, the mechanism for departing the EU, provides a two-year timeframe to reach an agreement, and failure to do so will result in automatic exit. The question is whether the UK and its 27 partner nations will have enough time to reach a mutually satisfactory agreement enshrining most of the bond they already share, or be forced into a much harsher break-up. Nobody knows the answer yet.
What does seem certain to me, however, is that these talks need to reach coherent outcomes. Nobody can be in and out at the same time, or enjoy privileges without fulfilling responsibilities. This has absolutely nothing to do with retribution: it is simple logic. No European government could agree to grant the UK free access to the single market if Britain does not accept rules, duties and concessions, including the free movement of Europeans, in return.
