A wider European Union could bring significant opportunities for Europe as a whole. Enlargement has the potential to strengthen the European economy, reinforce security and stability across the continent, and increase the EU’s influence on the international stage. The Commission’s latest Enlargement Package points to continued progress by several candidate countries towards EU membership, bringing the prospect of a larger Union closer and giving renewed impetus to the enlargement process.
Presented on 4 November, the Package takes stock of progress made by the candidate countries over the past year and sets out priorities for the next stages of accession. While reaffirming the established principles underpinning enlargement, it also seeks to translate renewed political momentum into more concrete negotiating objectives. The four indicative roadmaps for Montenegro, Albania, Moldova and Ukraine are its most tangible expression, providing a clearer picture of the different trajectories accession may take in the coming years.
The 2026 Enlargement Package
The Package consists of the Commission’s main Communication, 2026 Communication on EU Enlargement Policy, accompanied by individual reports on the ten partners. It also includes four indicative roadmaps for the countries considered most advanced in the accession negotiations.
The Communication places enlargement in a wider political, security and economic context. It examines the contribution of enlargement to Europe’s security and resilience, its economic opportunities, and the reforms required of candidate countries. It also considers the EU’s own preparations for a larger Union. In this respect, it builds on the Commission’s 6 October Communication, Preparing for a Wider Union, which addressed the institutional, policy and budgetary adjustments needed ahead of future accessions.
The fundamentals remain decisive
The Package confirms that the renewed geopolitical importance of enlargement does not change its underlying principles. The process remains merit-based, with progress determined by each candidate’s own achievements and, above all, by the implementation of reforms under the fundamentals.
Democracy, the rule of law, fundamental rights, functioning democratic institutions, public administration reform and the economic criteria continue to determine the overall pace of negotiations. The Commission places particular emphasis on implementation and enforcement: legislative alignment alone is insufficient without independent institutions, effective public administration and a sustained track record of results.
The country assessments illustrate the increasingly differentiated picture. Montenegro has made substantial progress on the rule of law and institutional functioning, while Albania has met the interim benchmarks under the fundamentals cluster. Moldova has advanced judicial and anti-corruption reforms, and Ukraine has continued its reform efforts despite Russia’s war of aggression. By contrast, the Commission identifies further deterioration in democratic standards, fundamental rights and the rule of law in Georgia and Türkiye. Bosnia and Herzegovina and Serbia have not made the necessary progress on the fundamentals.
The economic dimension also remains central. Economic convergence, competitiveness and the capacity to withstand competitive pressure within the EU are essential requirements. The Commission highlights the potential benefits of enlargement, including stronger European value chains, increased investment and the expansion of the Single Market. Realising these benefits, however, depends on structural reforms, sound economic governance and the effective implementation of the acquis.
Good-neighborly relations and regional cooperation remain important elements of the process, particularly in the Western Balkans. The Commission stresses the need for reconciliation and the peaceful resolution of disputes, while making clear that bilateral issues unrelated to accession criteria should not be incorporated into the negotiations as such.
Finally, alignment with the EU’s Common Foreign and Security Policy, including the implementation of restrictive measures and efforts to prevent sanctions circumvention, remains a key indicator of a candidate’s strategic orientation. The contrast between the high or full alignment maintained by Albania, Montenegro, Moldova and Ukraine and the low alignment of Serbia and Türkiye is particularly significant.
Taken together, the assessments confirm that the strategic importance of enlargement has not displaced conditionality. The fundamentals remain the indispensable basis for a credible accession process.
Preparing for the next enlargement
The Package also advances the discussion on the EU’s own preparations for enlargement. Building on the October Communication, the Commission stresses the need to adapt EU policies, institutions, governance and financial arrangements as negotiations progress, while ensuring that the Union remains capable of acting effectively with a larger membership.
One important element concerns safeguards in future accession treaties. The Commission envisages stronger provisions to ensure that commitments made during negotiations continue to be respected after accession. These would include a dedicated institutional safeguard addressing serious breaches of the values enshrined in Article 2 TEU and the principle of sincere cooperation. In the most serious cases, measures could include the suspension of Council voting rights. Transitional arrangements could also be used in sensitive areas such as the free movement of workers and services, agriculture, funding and participation in common EU systems.
Montenegro’s accession treaty will be the first to incorporate this strengthened approach, potentially providing a model for subsequent accessions.
The Package also introduces a common framework for more structured gradual integration before membership. This is intended to deepen cooperation in strategic sectors such as energy, transport, digital policy and defence, with participation conditional on progress and alignment with EU rules. Gradual integration is designed to bring tangible benefits to candidate countries while reinforcing the incentives for reform; it complements, but does not replace, the accession process.
Four roadmaps, four different trajectories
The most significant new element of the 2026 Package is arguably the presentation of individual roadmaps for the four front-runners. Setting out concrete milestones for the year ahead, they aim to organise the next stages of preparation more predictably and transparently, providing a framework for candidate countries, EU institutions and Member States. The Commission may adjust and update them depending on progress in meeting the required conditions.
Montenegro is approaching the final stage of negotiations. Having opened all 33 negotiating chapters and provisionally closed 21, it has made substantial progress over the past year. The Commission considers that the closing benchmarks have been met in all chapters and that the remaining chapters could be provisionally closed by the end of 2026, subject to Member States’ agreement. Work on the accession treaty is already under way, and the Council has adopted conclusions on the financial package. For the first time since Croatia’s negotiations were concluded in 2011, the EU is in a position to close negotiations with another candidate country.
Albania has made rapid progress in opening negotiations. It opened all negotiating clusters in just over a year and provisionally closed its first four chapters after meeting the interim benchmarks under the fundamentals cluster. Its objective is to conclude accession negotiations by the end of 2027. Achieving this will require maintaining reform momentum, fulfilling the remaining closing benchmarks and ensuring constructive political dialogue.
Moldova has also advanced considerably, having formally opened four of the six negotiating clusters. The Commission considers that the conditions for opening the remaining clusters have been met. Its objective is to close accession negotiations by early 2028, an ambitious but achievable target if the current reform momentum is maintained. The emphasis is increasingly on implementation and enforcement, particularly under the fundamentals.
Ukraine is following a similar negotiating path, but under substantially different circumstances. It has also opened four clusters, with the Commission considering that the conditions for opening the remaining ones have been fulfilled. Its objective is to close accession negotiations by the end of 2028. The roadmap underlines the need to accelerate reforms, particularly concerning the rule of law, democratic institutions and public administration, while recognising the exceptional circumstances created by Russia’s ongoing war of aggression.
The four roadmaps therefore reflect different stages of preparation and levels of ambition. Their milestones are indicative, conditional on continued progress and subject to regular review. They should not be interpreted as guaranteed accession timetables or as prejudging decisions to be taken by the Council.
Conclusions: What does this mean for the next enlargement?
The 2026 Package points towards a differentiated accession process. Although four countries are grouped together as front-runners, their negotiating trajectories are no longer identical.
This is particularly relevant for Moldova and Ukraine. Having opened the same four clusters, and with the Commission considering that both are ready to open the remaining ones, the two countries have so far advanced broadly in parallel. Their respective objectives, however, differ: Moldova aims to close negotiations by early 2028, while Ukraine aims for the end of that year. This raises the possibility that their accession processes could become decoupled. It is not a formal decision or an inevitable outcome, but the roadmaps provide a basis for considering separate negotiating trajectories.
Montenegro presents a different question. The Commission considers that negotiations could be concluded by the end of 2026, with work on the accession treaty already under way. However, the Commission’s assessment does not itself settle the political question of accession. The remaining negotiating steps require Member States’ agreement, while the accession treaty will ultimately need to be ratified by all Member States. The central question is whether the Commission’s assessment of Montenegro’s readiness will be matched by the necessary political commitment among the 27.
The political obstacles should not be underestimated. At the October European Council, Croatia intervened to remove the reference to concluding the provisional closure of all remaining chapters by the end of 2026 from the draft conclusions. Zagreb has linked its position to the resolution of eight outstanding bilateral issues with Montenegro, several of which it associates with Chapters 23 and 31. The final conclusions therefore merely take note of the Irish Presidency’s intention to work towards closing the remaining chapters, subject to Montenegro implementing the required reforms.
The position of the other enlargement partners remains a significant challenge. North Macedonia has yet to adopt the constitutional amendments to which it committed, while Bosnia and Herzegovina and Serbia have made insufficient progress on the fundamentals. Negotiations with Türkiye remain at a standstill, and Georgia’s accession process is de facto halted amid further democratic backsliding. These differences reinforce the principle that progress must depend on individual merits rather than a common regional timetable.
The Commission’s readiness to prepare similar roadmaps for other negotiating countries once they reach a comparable level of advancement is also significant. It suggests that this more structured approach could become a regular feature of enlargement policy.
Overall, the 2026 Enlargement Package does not change the established conditions for membership. Its significance lies in translating renewed political commitment into more concrete negotiating trajectories, while advancing preparations on the EU side. Whether these roadmaps lead to actual accession progress will depend not only on the candidates’ capacity to deliver reforms, but also on the willingness of Member States to take the necessary political decisions.
