Jeremy Wright, Britain’s attorney general, appeared before the United Kingdom’s highest court in early December to argue one of the most significant constitutional cases Britain has seen in recent history: a case that will determine whether a vote by Parliament is required before the government can begin formal steps to leave the European Union. A week later, Wright was in New York, assuring top global law firms and their clients that they should not be overly concerned about Brexit, the term used to describe Britain’s exit from the bloc.

He was there, he said, to tell them that despite the turmoil and uncertainty created by Brexit, Britain is open for business. “Everyone is looking for reassurance,” Wright told The American Lawyer during an interview at the U.K. Mission to the U.N. “It’s important that they understand that Brexit will be a negotiation, and that the British legal system will continue to be important in markets all over the world.”
