Associate EU Citizenship: The Debate

When the United Kingdom voted to leave the European Union in 2016, millions of people who had built their lives around the right to live, work and study anywhere in the EU suddenly faced losing something they had held since birth. For many UK nationals, the most painful part of Brexit was not the trade deals or the parliamentary battles — it was the loss of EU citizenship itself. Since then, an idea has refused to go away: could there be such a thing as associate EU citizenship, a status that preserves some of those rights without full membership? We want to walk you through where this debate came from, what has actually been proposed, and why it remains unresolved.

What Is Associate EU Citizenship?

Associate EU citizenship is not a legal status that exists in EU law today. It is a proposal — a hypothetical category that would sit somewhere between being a full citizen of an EU member state and being a third-country national. The idea is that certain people who have lost EU citizenship through no personal choice, such as UK nationals after Brexit, could retain a limited set of rights linked to free movement and residence.

The concept emerged in academic and legal circles after 2016, but it gained real political traction when the European Parliament took it up. Crucially, no article of the Treaty on European Union or the Treaty on the Functioning of the European Union currently provides for it. EU citizenship is, under Article 20 TFEU, tied to nationality of a member state — and only member states can grant or remove their own nationality.

The Legal Foundations and Limitations

Because EU citizenship is derivative, it cannot be granted directly by the EU institutions. The European Parliament can pass resolutions, and the European Commission can propose legislation, but any new status would almost certainly require treaty change agreed unanimously by all member states. That is a very high bar. Legal scholars have pointed to the case law of the Court of Justice of the European Union, particularly Rottmann, to argue that losing EU citizenship rights can be disproportionate — but the Court has never recognised a standalone associate status.

How It Differs from Full EU Citizenship

Full EU citizenship brings a broad package of rights:

• Free movement and residence across all member states
• Voting and standing in European Parliament elections
• Diplomatic and consular protection from any member state
• Access to the European Citizens’ Initiative
• Protection against discrimination on grounds of nationality

Associate citizenship, in the models discussed so far, would offer only a subset — most likely residence rights in the EU and perhaps limited free movement, without voting rights or EU-level political participation. It would be a pragmatic compromise, not a full restoration.

The Brexit Context: Why This Debate Matters

Brexit is the reason this conversation exists at all. When the UK left the EU on 31 January 2020, UK nationals automatically ceased to be EU citizens. Unlike a person who renounces their nationality voluntarily, they had no individual choice in the matter. The 2016 referendum was decided by a collective vote, yet the consequences fell on individuals — people who had lived in Spain, France, Germany or Ireland for decades.

The Impact on UK Nationals in the EU

Around 1.2 million UK nationals were living in EU member states at the time of the referendum. Many had never applied for citizenship of their host country, assuming their EU rights would continue. After Brexit, they had to secure their position through the Withdrawal Agreement, which protected the rights of those already resident before the end of the transition period. But free movement as a forward-looking right — the ability to move to another EU country in future — was gone.

The Gap Left by the Withdrawal Agreement

The Withdrawal Agreement was a remarkable piece of legal engineering, but it was also limited. It ring-fenced the rights of UK nationals already living in the EU and EU citizens already living in the UK. It did nothing for:

• UK nationals who wanted to move to the EU after Brexit
• People who had lived in the EU previously but returned to the UK
• Future generations born to UK nationals in the EU
• Those who missed registration deadlines or fell through administrative cracks

This is the gap that associate EU citizenship proposals try to fill.

Key Proposals and Advocates

The campaign for associate EU citizenship has been driven by a coalition of MEPs, civil society groups and legal experts. The most prominent organisations are New Europeans and British in Europe, both of which have lobbied the European Parliament and the Commission consistently since 2017.

The European Parliament’s 2019 Resolution

In February 2019, the European Parliament passed a resolution on the Withdrawal Agreement that included a specific call to examine associate EU citizenship. It asked the Commission and member states to consider whether UK nationals who wished to retain certain EU rights could be granted a form of associate status. The resolution was not binding, but it put the idea on the official record and gave campaigners a formal hook to keep pushing.

The European Citizens’ Initiative ‘Retain EU Citizenship’

The European Citizens’ Initiative is a mechanism that allows one million EU citizens from at least seven member states to ask the Commission to propose new legislation. Campaigners launched an ECI titled ‘Retain EU Citizenship’ aimed at protecting the rights of UK nationals. Although it did not reach the threshold, it demonstrated cross-border support and forced the Commission to respond formally. The ECI remains one of the few tools available to keep the issue alive without treaty change.

Arguments Against Associate EU Citizenship

Not everyone thinks this is a good idea. Legal and political opposition has been substantial, and understanding it helps explain why nothing has moved forward.

Legal Barriers in EU Treaties

The central objection is simple: EU citizenship is defined by the treaties as deriving from member state nationality. Creating a parallel status would require amending Article 20 TFEU, which means unanimous agreement among all 27 member states plus ratification by national parliaments. Several legal services, including the Council’s, have advised that associate citizenship cannot be created by secondary legislation.

Political Resistance from Member States

Beyond the legal hurdle, there is political reluctance. Some member states worry that associate citizenship would:

• Undermine the principle that EU citizenship is indivisible
• Set a precedent for other non-EU countries seeking similar arrangements
• Create a two-tier system that devalues full citizenship
• Complicate national immigration and residence policies

There is also a view that Brexit must have consequences, and that offering a workaround would blur the line between member and non-member.

What Could Associate Citizenship Look Like?

If it were ever created, what would it actually involve? Campaigners and academics have sketched several models.

Possible Rights and Limitations

Most proposals focus on a narrow set of rights:

1. Residence rights in a specific member state, renewable and not tied to employment
2. Limited free movement, perhaps for study or work, subject to national quotas
3. Access to healthcare and social security coordination
4. No voting rights in European Parliament elections
5. No right to consular protection or ECI participation

This would be a functional status, not a symbolic one — designed to solve practical problems rather than restore full belonging.

Lessons from the EU Settlement Scheme

The UK’s own EU Settlement Scheme offers an interesting comparison. It granted EU citizens already in the UK a settled or pre-settled status, with rights broadly similar to before Brexit. It was administrative rather than political, and it worked — millions applied. Some campaigners argue the EU could create a reciprocal scheme for UK nationals, effectively a unilateral associate status granted by the EU or by individual member states. So far, no member state has done so, though Ireland’s common travel area arrangements offer a partial exception.

The Future of the Debate

The debate is not over, even if the legal pathway looks blocked. Campaigners continue to press the European Parliament, and the Commission has not formally closed the door on future discussions.

Ongoing Campaigns and Legal Actions

New Europeans and British in Europe have supported individual legal challenges, including cases before national courts and the Court of Justice of the European Union, arguing that loss of EU citizenship rights was disproportionate. None has yet succeeded in establishing a right to associate status, but each case keeps the issue in the public eye.

The Role of the European Citizens’ Initiative

The European Citizens’ Initiative remains the most viable democratic tool. A future ECI with stronger cross-border organisation could force the Commission to reconsider. The Conference on the Future of Europe, which concluded in 2022, included citizen recommendations on citizenship and mobility, though it did not produce a specific mandate on associate citizenship. It did, however, show that EU citizens care about these questions.

FAQ

Is associate EU citizenship actually available to UK nationals now?

No. There is no legal basis for it in current EU treaties, and no member state or EU institution has created such a status. It remains a proposal only.

Did the European Parliament formally support it?

In its February 2019 resolution on the Withdrawal Agreement, the European Parliament called for the possibility of associate EU citizenship to be examined. The resolution was not binding and did not create any rights.

Could the European Citizens’ Initiative bring it back?

An ECI can prompt the Commission to consider legislation, but it cannot override the treaty requirement that EU citizenship derives from member state nationality. A successful ECI would keep the debate alive but would not by itself create the status.

What rights did UK nationals lose after Brexit?

They lost free movement across the EU, the right to reside in any member state without a visa or permit, voting rights in European Parliament elections, and access to the European Citizens’ Initiative. The Withdrawal Agreement preserved residence rights only for those already living in the EU before the end of the transition period.

Is there any alternative to associate citizenship for UK nationals?

Yes. UK nationals can apply for citizenship of an EU member state through naturalisation, often after five years of legal residence. Ireland also offers citizenship through descent for many people with Irish ancestry, which restores full EU citizenship.

Associate EU citizenship remains legally uncertain, but the debate reflects something real: a deep and enduring desire among UK nationals to keep their European ties and rights. Whether it ever becomes law depends on politics, treaties and the persistence of the people who refuse to let the issue fade.
