Post-Brexit sovereignty is becoming a contest between competing regulatory spheres.
LONDON, UNITED KINGDOM
US Trade Representative Jamieson Greer has accused Britain of favouring regulatory alignment with the European Union over deeper commercial integration with the United States. Greer argued that London’s reluctance to accept more products manufactured under American standards is obstructing efforts to expand the bilateral trade agreement negotiated in 2025. His statement represents Washington’s interpretation of British policy, not a formal declaration by the UK government that it has chosen Brussels over the United States.
The dispute centres particularly on agricultural and product regulations. Washington wants Britain to liberalise market access for American goods, while London has insisted that imported products must not weaken national food and safety standards. The existing agreement expanded access for US beef and ethanol while reducing American tariffs on British luxury cars, steel and aluminium. Britain also secured tariff protection for pharmaceutical exports after agreeing to higher prices for certain medicines.
Prime Minister Andy Burnham is simultaneously pursuing closer cooperation with the European Union, continuing the post-Brexit reset initiated by his predecessor, Keir Starmer. Burnham has argued that Brexit contributed to Britain’s weak economic growth and that closer European relations could reduce commercial barriers. A UK-EU summit expected before the end of the year may advance discussions on regulatory cooperation and other areas of economic coordination.
British alignment with European standards would facilitate trade with the EU, which remains the country’s largest commercial partner, but it could restrict London’s ability to accept products governed by different American rules. Greater alignment with Washington could produce new opportunities for British exporters while complicating access to the European single market. The government therefore faces a structural dilemma: regulatory divergence creates negotiating freedom, yet every major agreement can limit the freedom available in the next one.
Greer’s criticism also exposes the geopolitical dimension of modern trade policy. Standards governing food, medicines, technology and industrial products increasingly determine which economic sphere a country occupies. Britain may attempt to preserve strong relationships on both sides of the Atlantic, but Washington is signalling that selective alignment has consequences. The central challenge is no longer simply whether the United Kingdom can sign independent agreements after Brexit, but whether it possesses enough economic leverage to reconcile incompatible demands from its two most important external markets.
