Britain and the United States trade hundreds of billions of dollars' worth of goods and services annually, but London hopes that ambiguities in the data will help to earn it an exclusion from U.S. President Donald Trump's sweeping tariff plans.

After announcing levies on imports from Canada, Mexico and China, the president has hinted at expanding the meaures.
