Belgrade: Serbia EU accession faces its most uncertain autumn in years after President Aleksandar Vucic resigned on 27 September 2026 and called a snap parliamentary election for 25 October. Vucic quit seven months before the end of his second and final term to run for prime minister, leaving Parliament Speaker Ana Brnabic as acting head of state. Whoever forms the next government will inherit an accession file that has barely moved in five years.
The numbers explain the frustration on both sides. Serbia has been a candidate since 2012 and opened negotiations in 2014, yet no negotiating chapter has been opened since December 2021. In July, eight member states blocked the opening of Cluster 3. Enlargement Commissioner Marta Kos has meanwhile threatened to freeze 1.5 billion euros in pre-accession funds over stalled judicial reform, a warning that turns the election into a test of whether any government in Belgrade will deliver the rule-of-law changes the Commission demands.
The campaign over Serbia EU accession is polarised. Vucic’s Serbian Progressive Party is running as United Serbia against Students Win, an anti-corruption movement that grew out of the university protests, and European Serbia, a pro-Western opposition alliance. Those protests began after the collapse of a station canopy in Novi Sad on 1 November 2024 killed 16 people, and demonstrators blamed corruption and weak oversight of public construction contracts. Minutes before resigning, Vucic pardoned 49 people, 23 of them over alleged offences during the protests, a gesture the opposition will read as an attempt to clear the ground.
On Serbia EU accession, Brussels has been careful to keep its distance. Commission President Ursula von der Leyen toured Tirana, Podgorica and Skopje in early October but skipped Serbia and Bosnia and Herzegovina because of the election campaigns. The Commission is preparing new roadmaps for the most advanced candidates, Montenegro and Albania, which sharpens the contrast with a Serbia that has not opened a chapter in almost five years. The message is that merit, not geography, sets the pace.
For Serbia EU accession, the more difficult question is political rather than technical. A presidential election must be completed within 90 days, and Vucic has said the first round will be held by the end of December, so campaigning will dominate the coming months. Washington has also hardened its line, with a bill introduced in August that would sanction Serbian officials over Belgrade’s ties to Russia, China and Iran.
The practical test after 25 October is simple. A new government that wants Serbia EU accession to move must show progress on judicial reform, media freedom and alignment with EU foreign policy before member states unblock Cluster 3. Without that, the funds that Commissioner Kos has warned about could be the next casualty, and the accession file will stay frozen.
