Global Britain

Global Britain is the branding used by successive Conservative governments from Theresa May onward to describe the United Kingdom's post-Brexit international posture. The phrase entered official discourse in late 2016 and was given its fullest articulation in the March 2021 Integrated Review of Security, Defence, Development and Foreign Policy, titled Global Britain in a Competitive Age, and its 2023 refresh.

The concept rests on several pillars:

• Trade diversification beyond the EU, including new or rolled-over free trade agreements with Australia, Japan, and accession to the Comprehensive and Progressive Agreement for Trans-Pacific Partnership (CPTPP), signed in July 2023.
• An Indo-Pacific tilt, signalled by the 2021 deployment of the HMS Queen Elizabeth carrier strike group to the region and the September 2021 AUKUS security pact with Australia and the United States.
• Reinforced transatlantic and European security ties, particularly through NATO and bilateral support for Ukraine following Russia's February 2022 invasion.
• A continued role in global governance via the UN Security Council, G7, G20, and Commonwealth.

Critics, including parliamentary committees such as the House of Commons Foreign Affairs Committee, have argued the slogan lacks substantive content, masks reduced diplomatic capacity, and sits uneasily with the 2020 merger of the Department for International Development into the Foreign, Commonwealth and Development Office (FCDO) and the cut in Official Development Assistance from 0.7% to 0.5% of GNI.

Supporters counter that the UK has retained convening power, leveraged sanctions coordination on Russia, and used its independent trade policy to strike agreements unavailable as an EU member.

Under the Labour government elected in July 2024, Foreign Secretary David Lammy has largely retired the "Global Britain" label in favour of "progressive realism," though many of its underlying commitments — NATO, AUKUS, CPTPP — have continued.
