Potential re-accession of the United Kingdom to the European Union

The United Kingdom in orange; the European Union (27 member states) in blue

Following a 2016 referendum, the United Kingdom exited from the European Union at the end of January 2020. Since leaving the EU, numerous polling organisations have conducted surveys to gauge public opinion on rejoining the organisation. The trend of the poll data shows that, over time, support for Brexit has waned, while public opinion in the UK has gradually moved in favour of rejoining the EU (either totally, or partially, such as joining the European single market). ^[1]

History

A referendum on the United Kingdom's membership of the European Union took place in 2016, following the European Union Referendum Act being approved by parliament the previous year. ^{[2] [3]} Most political parties, including Labour and the Liberal Democrats, supported remaining in the European Union while the governing Conservative Party remained neutral, with the prime minister, David Cameron, supporting the UK remaining in the European Union. A majority of voters supported the UK leaving the European Union, with 51.9% voting in favour of leaving and 48.1% in favour of remaining. Cameron resigned, and was succeeded by Theresa May and, later, Boris Johnson, both of whom negotiated the terms of the UK's departure. The UK's departure from the European Union led to two early general elections in 2017 and 2019, and dominated British politics until 31 January 2020, when the country's membership of the European Union ended.

In September 2023, thousands of people participated in a march in London campaigning for the United Kingdom to rejoin the EU. ^[4] Also in September 2023, France and Germany proposed a restructuring of the membership of the EU to allow the UK to rejoin as an associate member, rather than a full member. ^[5] Associate membership would include membership of the European single market but not the EU customs union, in exchange for participation in the European Court of Justice and making contributions to the EU budget. ^[6] The president of the European Commission, Ursula von der Leyen, expressed her support for the UK eventually rejoining the EU. ^[7] In September 2023 Keir Starmer, leader of the Labour Party and the now-Prime Minister of the UK, ruled out the possibility of the UK rejoining the EU under a Starmer-led Labour government. ^[8]

Potential enlargement of the European Union is governed by Article 49 of the Maastricht Treaty. If the UK applied to rejoin the EU, it would need to apply and have its application terms supported unanimously by the EU member states. ^[9] In January 2020, the political scientist Anthony Salamone wrote that member state support would seek "significant, stable and long-lasting majority public opinion in favour of rejoining", suggesting sustained 60% support would be a plausible minimum. ^[9] New negotiated terms may also require the UK's participation in the Eurozone and Schengen Area, as well as offering fewer concessions than the UK previously received as a member. ^[9] Any concessions sought when joining would need unanimous support from member states and a majority in the European Parliament. ^[10]

Political positions

Some UK political parties have policy proposals for the United Kingdom, or its member countries, to rejoin the European Union in the future, while others have ruled out supporting it.

1. As an independent Scotland
2. The party stated in 2024 that this is a "longer term objective" ^[14]
3. As an independent Wales. The party also wishes for the UK to rejoin the single market and customs union immediately. ^[16]

An All-Party Parliamentary Group on Europe was set up in October 2024, with the aim of promoting closer ties with the EU. Its secretariat services are provided by the European Movement UK. ^[18]

Opinion polling

Graphical summary

The chart below shows opinion polls conducted about whether the United Kingdom should rejoin the European Union. The trend lines are local regressions (LOESS).

The blue line is rejoin and the red is stay out.

National polls

Polling of British voters on whether the United Kingdom should rejoin the European Union. Polling includes only those that explicitly ask how the responder would vote in a hypothetical referendum on the United Kingdom rejoining the European Union, rather than repeating the remain/leave question of the 2016 referendum.

Specialist opinion polling

Conditioning Accession on Euro Adoption

During the United Kingdom's membership of the European Union, it did not seek to adopt the Euro and attained an opt-out as a part of the Maastricht Treaty negotiations.

WeThink, the public polling arm of Omnisis, began including a supplementary question as a part of its Brexit polling assessing how Euro adoption would influence voting intentions on a hypothetical referendum on re-joining the European Union.

Question: A condition of rejoining might be the adoption of the euro as currency. If the UK did have to adopt the euro how do you think you would vote if there was a referendum on EU membership tomorrow?
