MEPs Clash with Commissioner Kos on Enlargement Pace and Conditionality in AFET Debate

Key political clashes emerged during the European Parliament’s AFET meeting on April 20, 2026, with Commissioner for Enlargement Marta Kos sparring with multiple MEPs over the pace of EU enlargement and the strictness of conditionality applied to candidate countries. Kos emphasized a merit-based enlargement approach combined with gradual sectoral integration, whereas some MEPs pressed for accelerated accession due to geopolitical security needs, highlighting tensions on EU enlargement strategy between maintaining current rigorous criteria and delivering faster political results.

The session, chaired by Michael Gahler (EPP), took place amid Europe's heightened security and geopolitical concerns, setting the stage for a nuanced debate on enlargement as central to peace and EU influence. Kos defended the Commission’s efforts to marry reform benchmarks with pre-accession benefits such as SEPA, roaming, and growth plans but also rejected allegations about her fitness for office, which several MEPs raised. This debate follows a series of high-level statements on enlargement in recent months. On November 18, 2025, Kos herself had outlined a robust vision for enlargement at the Enlargement Forum, emphasizing that progress must be credible with no shortcuts. Days earlier, on November 13, 2025, she had advocated for completing European unity through strict enlargement policy, articulating a three-pronged approach ensuring candidate states achieve full readiness. President Ursula von der Leyen, in a video message at the same November 18 forum, framed enlargement as a strategic investment in security and prosperity, while on January 23, 2026, she proposed substantial investments for Greenland and Ukraine. Commissioner Andrius Kubilius, on April 16, 2026, urged EU enlargement by 2030, citing Central Europe's role and the Russian threat.

Concrete policy proposals were notably presented by Kos, who detailed accession timeframe ambitions—Montenegro potentially joining by 2028 and Albania by 2030 if negotiations progress—and advocated for creating new institutional safeguards in accession treaties to prevent future backsliding. She also supported revising EU decision-making processes, including discussions on moving from unanimity to qualified majority voting in foreign policy. Conversely, many MEPs like Petras Auštrevičius (Renew) called for a real strategic enlargement plan possibly supported by a special summit to expedite geopolitical accession, while others like Thomas Waitz (Greens/EFA) demanded more clarity about tangible benefits beyond partial market integration. This echoes earlier calls by High Representative Kaja Kallas on November 4, 2025, who proposed maintaining a tough enlargement process with a 2030 aim, and Kos's own November 4, 2025, presentation of the 2025 Enlargement Package to the European Parliament, which emphasized early integration for candidate countries like Montenegro, Albania, Moldova, and Ukraine.

The debate highlighted cleavages on EU integration depth versus national sovereignty, notably concerning enlargement methodology. Kos favored enhanced gradual integration models—granting candidates sector-specific rights before full membership—drawing from existing arrangements with Norway and Switzerland, while some MEPs feared this could dilute accession standards or create uncertainty. There was also a split on conditionality enforcement: Michael Gahler (EPP) favored extending Ukraine’s stringent Ukraine Facility-style quarterly conditions to all candidates, whereas Kos underlined Ukraine’s exceptional context and current differentiated treatment. This tension reflects earlier positions: on November 2, 2025, Kos had proposed strengthening enlargement policy to enhance security and sovereignty, and on March 30, 2026, the EEAS pressed North Macedonia to accelerate public administration reforms. Additionally, on April 7, 2026, the European Medicines Agency issued a data protection notice for pre-accession assistance, indicating ongoing technical preparations.

Regarding follow-ups, the debate signals ongoing reflections in EU institutions on reforming enlargement methodology and conditionality mechanisms, alongside internal preparations like institutional and financial capacity upgrades. The emphasis on merging security concerns with reform benchmarks suggests that future enlargement discussions could increasingly balance pragmatism with traditional accession criteria. The dual focus on trust-building safeguards and flexibility in sectoral integration points to a possible shift in the enlargement framework, yet final approaches remain contingent on member state consensus.
