Almost exactly 12 months on from the result of the Brexit referendum, formal negotiations between the UK and the EU got under way this week. Both parties are entering into discussions knowing that neither will be in a position to claim a successful outcome. Whatever agreement is put in place, we can be sure that it will not be as beneficial to either party as the one that already existed. It is a strange point to be starting from in any set of negotiations.Nevertheless, the start of negotiations is a positive development in that the scope for political grandstanding has now been significantly reduced. The increased accountability has already led to a shift away from much of the rhetoric of the past few months as the reality of what Brexit means starts to dawn – particularly within Westminster. The negotiation process should for the first time give British voters a sense of what they stand to lose from Brexit and the benefits of the existing arrangement.
