The United Kingdom is a P5 permanent member of the UN Security Council, a nuclear power, and a founding NATO member. Post-Brexit, it has pursued 'Global Britain,' seeking to maintain influence through the AUKUS pact, Five Eyes intelligence, the Commonwealth, and bilateral defense agreements.

The UK has been one of Ukraine's strongest supporters, providing early and decisive military assistance. London remains a global financial center, and the UK's soft power -- the BBC, English language, universities, and cultural exports -- gives it influence far beyond its economic weight. The Commonwealth of Nations connects it to 56 countries across every continent.

MUN Delegate Guide

As the UK, project P5 authority and post-Brexit Global Britain ambitions. Coordinate closely with the US on security issues and with European partners on Ukraine and Russia.

Leverage the Commonwealth for coalition-building -- 56 countries across every region. Use your AUKUS and Five Eyes partnerships in Indo-Pacific discussions. Lead on development, humanitarian issues, and climate (COP26 legacy). Your defense capabilities and intelligence assets give you credibility on security issues that few other countries match.

Foreign Policy

Post-Brexit UK foreign policy balances the 'special relationship' with the US, Indo-Pacific engagement (AUKUS, CPTPP), European security partnerships, and Commonwealth leadership. Key priorities include Ukraine support, China competition, counterterrorism, and development through the FCDO.

The UK has sought Free Trade Agreements globally, joining the CPTPP and signing deals with Australia, New Zealand, and Japan. It remains Europe's largest defense spender and a key NATO contributor.
