Night falls in the European capital. Everything’s quiet, but the nightmares are about to begin.

Viktor Orbán’s ghost haunts the Schuman roundabout; ash from the bonfire of red tape covers the Justus Lipsius building; Ursula von der Leyen’s chief of staff, Björn Seibert, chases after staffers demanding to know what “associate membership” for Canada actually means; and MEPs tremble at the prospect of construction workers uncovering the skeletons of political intrigues past during renovations.

Scared? You should be.

Here’s our guide to who is terrified of whom in the Brussels bubble. 

Everyone is scared of Marine Le Pen

The person haunting EU diplomats, officials and lawmakers is French presidential front-runner Marine Le Pen. Will she really halve Paris’ contribution to the EU budget, as promised? Will she pull Italian Prime Minister Giorgia Meloni away from the Brussels mainstream? And will she demand von der Leyen’s head?

The bubble had warmed (slightly) to the idea of Jordan Bardella in the Élysée Palace, after his years leading the National Rally’s European operation revealed a certain pragmatism toward Brussels — only for those hopes to be shattered when a Paris appeals court cleared Le Pen to be a candidate for the presidency.

The next ECB chief is scared of Jean-Luc Mélenchon

The European Central Bank president is the euro’s last line of defense against unorthodox national economic decisions — but that could be tested by French presidential candidate Jean-Luc Mélenchon, who is on course to reach the runoff after vowing to set billions of euros of French debt “on fire.” His incendiary plan calls on the Frankfurt-based ECB to waive interest payments on a vast tranche of French bonds — an unorthodox, perhaps impossible, maneuver that critics warn could even see France kicked out of the euro.

Now that we know Christine Lagarde will step down as ECB president in February, what France’s presidential candidates want to do about its monumental debt pile will haunt the race for her successor, with Dutchman Klaas Knot and Spaniard Pablo Hernández de Cos as the two frontrunners.

Lobbyists are scared of ChatGPT

The number of amendments lawmakers have filed has exploded since generative AI arrived, with key EU laws now facing thousands of proposed text changes. Parliament officials don’t think it’s a coincidence, with some pointing to amendments written in suspiciously bot-like language, and others saying sometimes amendments cite legislation that does not even exist.

The growing pile of amendments is haunting lobbyists, parliamentary assistants and officials forced to track and sort through it all — along with the fear that AI could eventually replace them. Spare a thought, too, for the MEPs who may have to vote through the amendments one by one, with hands raised in plenary. 

Commission officials are scared of Austria’s Europe minister

Well-heeled Commission officials (and their families) are spooked by Austria’s Europe Minister Claudia Bauer, who has been leading a push to slash the Commission’s administration expenditure — which pays eurocrats’ salaries and offices — in the next seven-year budget. The campaign, backed by most EU capitals, resulted in an 8% cut to the admin budget in the latest budget proposal.

Bauer is so feared that EU officials joke they reduce their delegations’ size whenever they travel to Austria.

Jessika Roswall is scared of Stéphane Séjourné and Valdis Dombrovskis

Environment Commissioner Jessika Roswall and her department have reason to fear industry boss Stéphane Séjourné, who is taking the lead on the upcoming Circular Economy Act, despite Roswall’s official title of Commissioner “for a Competitive Circular Economy.” Making matters spookier, Roswall’s environment department now shares the Breydel building with Séjourné’s internal market and industry department, setting the stage for some chilling corridor encounters as Roswall pushes for greater environmental protection while Séjourné prioritizes industrial growth.

Roswall is also under pressure from EU simplification chief Valdis Dombrovskis to cut red tape on several environmental laws. The Latvian commissioner, who oversees the omnibus packages, wants a deal before year-end. Meanwhile, the center-right European People’s Party continues to press the Commission to reopen laws on birds, habitats, and water — the EU’s oldest nature protection laws — so they can be simplified too.

Alexander Stubb is afraid of Kaja Kallas and António Costa

Kaja Kallas has not publicly addressed the call that Finnish President Alexander Stubb made to Russia’s Vladimir Putin, but the EU’s top diplomat has made clear she dislikes such outreach. Still, if Putin offered serious talks and concessions, Kallas would be the obvious person to answer: as coordinating EU foreign and security policy is her job. “Of course I will talk if such an opportunity presents itself,” she told Estonian media in September when asked about speaking with Putin or his Foreign Minister Sergei Lavrov.

Also reaching for the phone: António Costa. EU diplomats note that the European Council president represents the bloc at the leaders’ level abroad. That institutional turf war may explain why Stubb stressed that he and Norwegian Prime Minister Jens Støre spoke only for their own countries — not for Europe.

Manfred Weber is scared of his own group …

What keeps the leader of the European People’s Party — Europe’s largest political family — up at night? Divisions within his own ranks. So far, Weber has kept a tight ship and wants to reunite his troops ahead of the 2029 EU election, which he is casting as a battle against the far right. But that may prove tricky as the EPP’s national delegations increasingly clash over whether to work with the far right or isolate them.

… and the group is scared of Ouarda Bensouag

Central to Weber’s strategy is Ouarda Bensouag, the group’s secretary-general and his chief of staff. One of his most trusted lieutenants, she has a reputation as a smart but ruthless operator who EPP staffers fear when crossing paths in the Parliament’s labyrinthine hallways.

No one is scared of the Parliament … but they should be

Parliament’s attempts to spook capitals over the next long-term budget have been borderline tragic so far: It keeps threatening to kill the budget, but nobody seems to care or believe it will.

They should care. When it comes time to pass the budget, 361 of 720 votes will be needed, and the margin could be razor-thin in a fragmented chamber that’s hostile to plans to pool farm and regional funds. The louder MEPs protest — and the longer the Council ignores them — the more determined they become to prove the threat is real.

BELGRADE — Brussels has lost its man in Belgrade.

The opposition Student List’s landslide victory on Sunday ended Aleksandar Vučić’s 12-year run as the EU’s key interlocutor in Serbia. For more than a decade, every step of the candidate country’s accession process and trade negotiations had to pass through him.

“Aleksandar Vučić acted like the go-to person for everything while ignoring all the laws in the country, including the constitution,” Jugoslav Gašić, an assistant professor in medicine at several universities and soon-to-be MP, said in an interview.

When POLITICO reached him, Gašić was in the middle of grading student papers — a fitting snapshot of a new parliamentary majority made up largely of professors, doctors and other political novices.

The Student List won an outright parliamentary majority at the weekend: a stunning result for a leaderless movement born out of protests.

The party’s first order of business will be undoing much the legacy of Vučić and his Serbian Progressive Party (SNS), starting with reversing years of rule-of-law rollbacks. But it will also reset Serbia’s relationship with Brussels, which the Student List argues the former leader managed more as a transactional tool than a genuine path to EU membership.

“Ultimately, [Vučić] always represented his own interests and not the interests of Serbia,” said Gašić.

Representatives for the SNS didn’t immediately respond to a request for comment.

Even among Serbia’s most committed pro-Europeans, Brussels’ willingness to route all progress through Vučić personally has left a bitter aftertaste.

“The key lesson that should be drawn from the case of Serbia is that the EU can very easily lose credibility and integrity if it ignores the causes of democratic backsliding in a country,” said Srdjan Majstorović, chairman of the governing board of the European Policy Center (CEP), a think tank.

According to CEP data published earlier this year, as many 41.6% of citizens believe the EU is more interested in pursuing its own political and economic interests in the region than improving the state of democracy and the rule of law in the country.

For years, anytime non-governmental organizations, journalists or activists argued that Brussels should try to include other voices in the EU negotiation process, they were told “that there was no alternative to the regime in Serbia,” Majstorović continued.

The Student List’s election program casts the EU as Serbia’s most important economic partner and pledged to deepen Belgrade’s existing strategic partnerships with EU members such as Greece, Italy, Hungary and France, while seeking closer bilateral ties with other European capitals.

It does not, however, explicitly name EU membership as an immediate goal.

Gašić wouldn’t be drawn on concrete aims for the Serbia-EU relationship, but said: “We don’t want to be cut off by Europe. We don’t want to be an isolated island.”

“I respect how well-ordered they are, the rule of law and democratic principles,” he added. “Yet I think we need to reset our priorities with the EU, where we consider Serbia’s interests first. A one-sided approach doesn’t foster long-term cooperation.”

The Student List grew out of a mass protest movement sparked by a 2024 railway station roof collapse that killed 16 people. Students blamed the deaths on corruption in state construction contracts and began blockading universities, and within months the protests had swelled into the largest Serbia had seen in decades.

Brussels’ response was muted as students marched across the country, with EU officials largely avoided criticizing Vučić directly. EU flags were conspicuously absent from the demonstrations.

The European Commission didn’t respond to a request for comment for this article.

“The Commission must first restore its long-lost credibility after years of propping up Vučić,” said Djordje Bojović, a foreign policy advisor for Greens in the European Parliament.

He said that Serbia has long been demonized and struggled to reinvent its image since the 1990s, an image “only further cemented by Vučić’s repressive authoritarianism.”

Despite those concerns, Serbia’s economic ties with Europe flourished during Vučić’s time in power, with the country becoming one of the region’s leading destinations for foreign investment.

Under Vučić, Serbia went from about €750 million in foreign direct investment in 2012 to more than €30 billion over the following decade, more than the rest of the Western Balkans combined.

In Brussels, figures such as Bojović and representatives of the opposition parties would plead with institutions such as the Parliament and the Commission to meet with them or take their concerns seriously.

“Vučić had convinced all of them that the opposition is not worth talking to and that they’re not credible,” Bojović said.

Now, with SNS firmly relegated to the opposition, Brussels will need to rethink how it works with Serbia. To many Serbians, the EU has 12 years of looking the other way to answer for first.
