But we cannot prosper at home unless Britain plays our indispensable role in maintaining the stability and security of the world. It is the right thing to do, but it also means that global Britain is of direct benefit to all our constituents. Millions of British jobs depend on the benign and transformative power of free trade. Last year, we sold goods and services worth almost £100 billion to the United States. Our exports rely, therefore, on other countries being rich and peaceful enough to buy our British products.
