In 1939, President Franklin D Roosevelt offered a toast to King George VI in the White House. “I am persuaded that the greatest single contribution our two countries have been enabled to make to civilisation, and to the welfare of peoples throughout the world,” he said, “is the example we have jointly set by our manner of conducting relations between our two nations.”

Nearly 80 years later, the United Kingdom remains a friend and ally to the United States like no other. Our special relationship was forged as we spilt blood together on the battlefield. It was fortified as we built and sustained the architecture for advancing stability and prosperity in Europe, and our democratic values around the globe. From the ashes of war, those who came before us had the foresight to create the international institutions and initiatives to sustain a prosperous peace: the United Nations and Nato; Bretton Woods, the Marshall Plan, and the European Union. Their efforts provided a foundation for democracy, open markets, and the rule of law, while underwriting more than seven decades of relative peace and prosperity in Europe.
