Brexit myths, checked against the facts

The biggest benefit is that Britain left

The aim of Brexit was to leave the EU and take Britain's decisions in Britain again. That has happened. Parliament is supreme, UK courts have the final say, and every law can be changed by people the public elects and can remove.

Everything else follows from that. The freedoms listed here are what independence looks like in practice, and Britain would have none of them had it stayed.

• The last word on law. Since 1 January 2024 EU law no longer overrides Acts of Parliament, and the EU's court no longer rules on Great Britain.
• £12.6bn down to £0.7bn. What Britain paid the EU, net, in 2020 and in 2025.
• No share of €807bn of EU debt. The EU's joint borrowing since 2020 is being repaid by its members until 2058. Britain owes none of it.
• Control of the border. Free movement ended on 1 January 2021. Parliament now decides who can come to live and work here.
• Britain's own trade deals. India, Australia, New Zealand and the 12-nation Pacific partnership, plus a 10% US tariff on British cars against 15% on EU cars.
• And the economy kept growing. The UK economy grew 17.1% over 2021–2025, faster than Germany (4.5%), France (13.8%) and Italy (16.7%).

Not what the growth figures show

Since the transition period ended, the UK economy has grown faster in total than Germany, France or Italy, using the IMF's own figures.

Forecasters such as the OBR assume a long-run productivity cost of about 4%. That is a modelling assumption about a world that did not happen. It cannot be measured directly, and the whole of Europe's big-four economies have had a hard decade.

• Real GDP growth 2021–2025 (IMF): UK 17.1%, Italy 16.7%, France 13.8%, Germany 4.5%.
• In 2025 the UK grew 1.3%, faster than France (0.9%), Italy (0.5%) and Germany (0.2%).
• By Q2 2026 UK GDP was 6.3% above its pre-pandemic peak; Germany's was 1.9% above.

There is no growth engine to plug back into

The EU's largest economy, Germany, has barely grown since 2019. The IMF expects Germany, France and Italy to grow between 0.5% and 0.9% in 2026.

Re-entry would also take years, cost the UK its current trade deals, and come on worse terms than before (see The Rejoin Reality).

• Germany's GDP in 2025 was only about 0.2% above 2019 (IMF).
• IMF 2026 projections: UK 0.8%, Germany 0.8%, France 0.9%, Italy 0.5%.
• Membership would end independent UK deals such as CPTPP, because trade policy is an exclusive EU competence.

EU members were hit just as hard

The price shock of 2022 was driven by energy costs after Russia invaded Ukraine. It hit countries inside the EU as hard as the UK, and in several cases harder.

Some studies find extra border checks added to food prices. But EU membership did not protect the Netherlands, Italy or Germany from inflation at or above UK levels.

• UK inflation peaked at 11.1% (October 2022).
• Eurozone average peak: 10.6% (October 2022).
• Germany 11.6%, Italy 12.6%, Netherlands 17.1% at their 2022 peaks.

UK courts once set aside Acts of Parliament

Under the European Communities Act 1972, EU law took priority over UK law. In the Factortame case (1990), UK courts disapplied part of an Act of Parliament because it conflicted with EU law.

That can no longer happen. EU law's supremacy in UK law was abolished from 1 January 2024.

• European Communities Act 1972 repealed by the EU (Withdrawal) Act 2018.
• The European Court of Justice's jurisdiction over Great Britain ended on 31 December 2020.
• Retained EU Law (Revocation and Reform) Act 2023, section 3: the principle of EU law supremacy no longer applies.

The NHS got far more

The health budget for England has risen from £120bn in 2016/17 to £204.7bn in 2024/25. That is an extra £1.6bn every week, more than four times the figure on the bus.

In fairness on both sides: the £350m was a gross figure that ignored the rebate, and the statistics watchdog criticised it. And the extra NHS money came from tax and borrowing as well as from EU payments that stopped, so it cannot be traced pound for pound.

• Health spending per week: about £2.3bn in 2016/17, about £3.9bn in 2024/25.
• After inflation, health spending grew by 3.1% a year on average between 2015/16 and 2023/24.
• In June 2018 the government announced £20bn a year more for the NHS by 2023/24, worth £384m a week in real terms, funded "in part" from money no longer sent to the EU.

The crossings began while Britain was still in

The Dublin rules let a country send an asylum seeker back to the first EU country they reached. Small-boat crossings started in 2018 and rose 28-fold by 2020, all while the UK was still covered by those rules.

Dublin returned very few people. From 2016 the UK took in more asylum seekers under it than it sent back. Research on why people choose Britain points to the English language, family already here and how often claims succeed. Oxford's Migration Observatory notes that many asylum seekers have limited information about the policies of the country they are heading for.

• Small-boat arrivals: 299 in 2018, 1,843 in 2019 and 8,462 in 2020, the UK's last year under Dublin.
• Later years: 28,526 in 2021, 45,755 in 2022, 36,816 in 2024 and 41,472 in 2025.
• In 2020 the UK sent 105 people to EU countries under Dublin and received 882. Fewer than 1 in 10 UK requests succeeded after 2016.
• Across 2008 to 2020 the UK transferred an average of about 560 people a year.

Those are model estimates, not measurements

Nobody can observe the Britain that stayed in the EU. Every figure for the "cost of Brexit" compares the real economy with an invented one, and the answer depends on how that invented Britain is built.

In fairness: most economists think leaving has had some cost, and the official forecaster says its assumption is broadly on track. But the largest figures rest on the weakest comparisons, and the economy's actual record is better than any of them implied.

• The 4%. This is an assumption the Office for Budget Responsibility set in March 2020, averaged from outside studies written before the trade deal was agreed. It calls the range of estimates "wide" and expects the effect to take 15 years. Britain Unbound notes that 9 of the 13 studies behind it put the cost below 4%.
• The 8%. A 2025 American study compared the UK with a group of other countries and blamed the whole gap on Brexit. That cannot separate Brexit from the pandemic, the energy shock or America's spending boom.
• The "doppelgänger" 5.5%. Almost a third of that comparison was the United States. UK growth tracked Germany's both before and after 2016.
• What can be measured. Since 2016 the UK has grown about 1% less in total than its European peers. Since 2021 it has outgrown Germany, France and Italy.
• A critic's own figure. Professor Jonathan Portes, of UK in a Changing Europe, puts the cost at 2% to 3% and calls that "a subjective assessment, not a quantitative model".

The EU is not Europe

Europe is a continent of more than 40 countries. The EU is a political union of 27 of them. Britain left the union. It did not leave the continent, and it cannot.

Good relations with neighbours do not need a shared government. Norway, Switzerland and Iceland are European, prosperous and outside the EU. Britain works with its neighbours every day on defence, trade, science and security, as an independent country.

• Defence. The UK is a leading member of NATO, which defends Europe, and one of Ukraine's biggest backers.
• Europe's wider clubs. The UK belongs to the 46-nation Council of Europe, the European Political Community and the Organization for Security and Co-operation in Europe.
• New treaties with neighbours. A friendship treaty with Germany was signed in July 2025, alongside long-standing defence treaties with France.
• With the EU itself. Tariff-free, quota-free trade under the 2020 trade agreement, a security and defence partnership agreed in May 2025, and membership of the Horizon science programme since 2024.

Controlling a border is what every country does

Almost every country in the world decides who may come to live and work there. So does the EU, which has its own border force and has set aside €5bn for migration and border management in 2026. Debating the numbers and the rules is ordinary democratic politics.

Since 2021 Britain has applied one set of rules to people from every country. Inside the EU it had to give Europeans priority over everyone else. Racism exists and should be condemned wherever it appears. It is a separate question from how many people a country admits and on what terms.

• Why people voted Leave. 49% said their main reason was that decisions about the UK should be taken in the UK. 33% said control of immigration and borders.
• Who voted Leave. A third of Asian voters and more than a quarter of black voters backed Leave (33% and 27%).
• One of the most welcoming countries. In a 2022 study of 17 countries Britain was the most accepting of immigration. 31% wanted strict limits or a ban, against 35% in Germany and 39% in Canada.
• Still true today. Oxford's Migration Observatory says opinion has become less supportive recently, but the UK is still more positive than many of its European neighbours.
