Britain in the world
A top-table country with its own voice
Britain is the world's fifth-largest economy and fourth-largest exporter, a permanent member of the UN Security Council and a member of the G7, G20, NATO, Five Eyes and AUKUS. It sits at each of these tables in its own right, and since leaving the EU it also speaks for itself on trade.
Where Britain stands
One of the world's leading powers, in its own right
A common worry is that Britain counts for less outside the EU. These are the rankings today.
4th
Largest exporter in the world
Britain exported $1.14 trillion of goods and services in 2024, ahead of France, the Netherlands and Japan, all of which it overtook in 2022. In services alone it is second only to the United States.

London ranks second to New York. Frankfurt and Paris are both outside the top 20.

In fairness: Britain held most of these rankings as an EU member, and it has slipped on two. London was ranked first among financial centres until 2018 and is now second, and Britain fell from third to fourth of 193 nations for soft power in 2026 (Brand Finance). The export ranking rests on services: for goods alone Britain is 14th (World Trade Organization, 2024). It remains in the first rank on every other measure here. Sources
Who sits where
Britain's seats, and the EU's
Britain is a full member of every body below. The EU is a member of some, an observer at others and absent from the rest.
| Body | Britain | The EU |
|---|---|---|
| UN Security Council | One of five permanent members, with a veto | Not a member of the UN. An observer at the General Assembly since 1974, with no vote |
| G7 | One of the seven members | Attends, but cannot chair or host |
| G20 | Member. Holds the presidency in 2027, with the summit in Manchester | Member |
| NATO | Founding member, 1949 | Not a member |
| World Trade Organization | Its own seat, voice and vote | A member alongside its states. The Commission speaks for all of them at almost all meetings |
| International Monetary Fund | Its own seat on the board, one of seven countries to have one | Not a member |
| Commonwealth | One of 56 nations, with the King as its head | Not a member |
| Pacific trade partnership (CPTPP) | Member since December 2024 | Not a member |
| Five Eyes | One of five members of the intelligence alliance with the United States, Canada, Australia and New Zealand, dating from 1946 | Not a member |
| AUKUS | One of three members of the security partnership with the United States and Australia, announced in 2021 | Not a member |
| OECD | Founding member, 1961 | Not a member. The Commission takes part in its work |
| Joint Expeditionary Force | Leads this force of ten northern European nations | Not a member |
| North-East Atlantic Fisheries Commission | Its own seat since October 2020 | One seat for all 27 members |
| Council of Europe | One of 46 members | Not a member |
As an EU member Britain kept its own seats at the UN, NATO, the G7 and the IMF, as France does today. At the World Trade Organization the Commission spoke for it, and on the fisheries commission it had no seat of its own. Sources
One voice, or one of 28
Would the EU speak for Britain?
On trade it would, from day one. On foreign policy the treaties point the same way, and leading voices in the EU want to go further. Here is what is law today, what has been proposed and what would not change.
The law today
Already in the treaties
- Trade. Only the EU can sign trade deals for its members. At the World Trade Organization the Commission speaks for every member state at almost all meetings.
- International bodies. Members "shall uphold the Union's positions" wherever they sit (Article 34, Treaty on European Union).
- The UN Security Council. EU members on the Council must defend the EU's positions and interests, subject to their duties under the UN Charter. When the EU has a position, they must ask for the EU's foreign policy chief to present it.
- Fishing. Britain's own seat on the North-East Atlantic fisheries commission would go back to the EU.
The direction of travel
Already proposed
- An EU seat at the UN. In March 2023 the European Parliament voted by 451 to 133 to recommend an "own and permanent seat for the Union" in world bodies, including the Security Council.
- EU embassies. The same vote called for EU delegations to become "genuine EU embassies".
- No more vetoes. In May 2023 nine governments, including Germany and France, formed a group to replace unanimity in EU foreign policy with majority voting.
- France's UN seat. In 2018 Olaf Scholz, then Germany's finance minister, proposed that France turn its permanent seat into an EU seat. France refused.
- The IMF. In 2015 the Commission proposed a single seat for the whole euro area by 2025. Member states have not agreed.
In fairness
What would not change
- Britain would keep its permanent UN seat and its places in NATO and the G7. France is an EU member and holds all three.
- British embassies would stay open. Every EU member runs its own.
- EU foreign policy still needs every member to agree, so Britain would have a veto. That is the rule the nine governments want to change.
- None of the proposals in the middle column is law. They show where many in the EU want to go.

Commissioners
Each member state has one. By treaty they may not take instructions from any government, including their own.
Treaty on European Union, Article 17
About 13%
Britain's share of the population vote
Most EU laws pass when 55% of member states with 65% of the EU's population agree. Britain could be outvoted, as it was before.

Trade deals Britain could sign for itself
Its agreements with India, Australia, New Zealand and the Pacific partnership would end or pass to Brussels.
Treaty on the Functioning of the EU, Article 3
Embassies and consulates
Would EU embassies replace British ones?
No. Nothing in today's treaties closes a national embassy. But the EU has built a diplomatic service of its own, and its Parliament wants it to become something more.

MEPs who voted for "genuine EU embassies"
The European Parliament recommended in March 2023 that EU delegations be converted into embassies. It is not law.
European Parliament recommendation, 15 March 2023
What the treaty says
National embassies and EU delegations must work together to make sure the EU's agreed positions are "complied with and implemented" (Article 35, Treaty on European Union).
What that would mean
A British ambassador would still be in post. Wherever the EU had agreed a line, he or she would be expected to uphold it.
What Britain has now
Its own ambassadors, answering to one government, which answers to Parliament and to voters.
Since leaving
Britain has acted in its own name
Not all of these needed Brexit, and we have marked the ones that did. Together they show a country that has not been sidelined.

Britain speaks, negotiates and votes for itself at the World Trade Organization.
