Belgrade: Serbia EU accession enters the autumn with its political script rewritten, because President Aleksandar Vučić dissolved Parliament on 9 September 2026 and called snap elections for 25 October. The vote lands in the middle of a Council debate over whether Belgrade has earned the right to open Cluster 3, the competitiveness bundle that has waited for years. Brussels must now judge a reform record and an electoral contest at the same time.
Serbia applied for membership in 2009, won candidate status in 2012 and opened negotiations in 2014. Twenty-one chapters are open, alongside the chapter on normalising relations with Kosovo, yet only Chapters 25 and 26 are provisionally closed. That record shows how slowly Serbia EU accession moved even before the current crisis, which began when the Novi Sad station canopy collapsed on 1 November 2024, killed 16 people and sparked a student-led protest movement.
The Commission made its case for Cluster 3 in an information note dated 3 July. It argues that Belgrade has repaired earlier backsliding by repealing the judiciary laws that the Venice Commission had criticised, and Enlargement Commissioner Marta Kos called the repeal an important step in the right direction. The decision still rests with the Council, where opening a cluster requires unanimity.
Capitals are divided. Some diplomats argue that rewarding the implementation of Venice Commission advice encourages reform elsewhere in the Western Balkans, while others say the repeal only returns Serbia to square one and that Cluster 1, which covers the rule of law, is the real test. Serbia’s refusal to align with EU sanctions on Russia weighs on Serbia EU accession and adds further weight to the sceptics’ case.
The election has already reshaped Brussels’ calendar. Ursula von der Leyen postponed a planned October trip to Serbia and Bosnia and Herzegovina after the Balkans in Europe Policy Advisory Group warned that a visit could be read as endorsement of the authorities. She had earlier called the presence of senior Serbian officials at the 7 September funeral of Ratko Mladić deeply regrettable. Meanwhile the student movement has put forward a 250-member list that one analyst believes could win more than 30 percent of the vote.
Money sharpens the stakes. Around €1.5 billion under the Western Balkans Growth Plan could be frozen over concerns about judicial reform and media independence, and the Commission’s 2025 report rated progress in key areas as limited. Those figures give Brussels leverage over Serbia EU accession, but leverage works only if the Union applies it consistently before and after the ballot.
The sober reading is that Serbia EU accession will be decided less by technical benchmarks than by the credibility of the 25 October vote. If the campaign is free and the next government keeps the judicial repeal in place, Cluster 3 becomes easier to defend in the Council. If not, the Union will have to explain why it opened new chapters regardless, and that answer will matter well beyond Belgrade.
