One vacancy will spark the chain reaction
As summer fades, Brussels prepares for one of its most consequential internal transitions in years — a cascade of senior departures within the European Commission set to ripple across the bloc's most influential directorates. Beginning with the retirement of a long-serving enlargement chief, the reshuffle will test the Commission's ability to renew its leadership while preserving institutional coherence at a moment of heightened geopolitical pressure. Behind the procedural choreography lies a deeper question familiar to all large institutions: whether the right people will find themselves in the right places when the autumn's demands arrive.
- A single retirement in the enlargement directorate is poised to set off a chain reaction of promotions and vacancies stretching across external relations, financial services, and humanitarian aid.
- France's EU ambassador Philippe Léglise-Costa is the most closely watched figure — a man reportedly willing to decline a major Commission role while waiting for a diplomatic prize that may not open until 2027.
- The financial services succession race is already contested, with three credible candidates maneuvering for a post that will shape the bloc's regulatory agenda for years to come.
- The Commission's September retreat in Ireland — themed simply 'reflection' — signals that von der Leyen's inner circle is seeking to reset internal dynamics before the autumn workload intensifies.
- All officials named in the reshuffle discussions declined to comment, and the Commission refused to engage with speculation, leaving the corridors of Brussels to fill the silence.
Brussels is already looking past summer toward September, when a cascade of senior departures at the European Commission will set off a chain of promotions and transfers reshaping the bloc's most powerful departments. The sequence is expected to begin with the retirement of Gert Jan Koopman, the Dutch veteran who has led the enlargement directorate since 2014. His exit would almost certainly elevate Michael Karnitschnig from his current post overseeing the Middle East and North Africa directorate — a move that would itself leave a vacancy drawing names like Despina Spanou and, in a telling sign of the Commission's habits, prompt another raid on the European External Action Service for senior talent.
The deeper intrigue surrounds the possible consolidation of the Commission's external relations machinery into a single super-directorate. The frontrunner for such a role would be Philippe Léglise-Costa, France's EU ambassador since 2017 and a figure with strong ties to Commission President von der Leyen's inner circle. Yet officials familiar with his thinking suggest he may be holding out for something grander: the EU Council secretary-general position, a post he lost to fellow French diplomat Thérèse Blanchet in 2022. With Blanchet not expected to step down before late 2027, at least one EU diplomat has called the wait impractical. Poland's ambassador Agnieszka Bartol is also considered a serious contender for that role.
Elsewhere, the succession race for the financial services directorate is already well underway ahead of John Berrigan's end-of-September retirement. Three names circulate persistently: Paulina Dejmek Hack, recently appointed deputy director and cabinet chief for Commissioner Roswall; Michael Hager, a trusted aide to Commissioner Dombrovskis; and Mario Nava, whose promotion would itself trigger another vacancy. The humanitarian aid directorate faces a similar transition with Timo Pesonen's expected departure before year's end.
The timing is deliberate. On September 2, the full College of Commissioners will travel to Ireland for its annual retreat — this year themed simply 'reflection' — a week after the traditional gathering of cabinet chiefs. Last year's retreat was marked by team-building exercises following a period of internal friction. The combination of sweeping personnel changes and a reset gathering suggests that von der Leyen and her closest advisers are engineering a recalibrated leadership structure before the pressures of autumn fully arrive.
Brussels is already looking past summer toward September, when a cascade of departures among the European Commission's most senior officials will set off a chain reaction of promotions and transfers that could reshape the bloc's most powerful departments. The dominoes are expected to start falling when Gert Jan Koopman, the Dutch veteran who has run the Commission's enlargement directorate since 2014, retires on January 1. His exit will almost certainly clear the way for Michael Karnitschnig, currently holding the top job at the Middle East and North Africa directorate, to move up—a promotion that will leave his current post vacant and trigger a series of moves across the Commission's sprawling bureaucracy.
Karnitschnig's ascent would open the Middle East and North Africa directorate to new leadership, and several names are already circulating among EU officials. One strong candidate is Despina Spanou, currently the deputy director-general at the digital services directorate. Another near-certain move, according to officials tracking the reshuffle, is Olivier Bailly's transfer from the EU's diplomatic service to become the deputy head of the Middle East and North Africa directorate—yet another instance of the Commission raiding the European External Action Service for senior talent to fill its own ranks.
But the real intrigue centers on a potentially much larger overhaul of the Commission's external relations machinery. The bloc has been weighing whether to consolidate several services into a single super-directorate, and if that happens, one name dominates the speculation: Philippe Léglise-Costa, France's ambassador to the EU since 2017. Léglise-Costa has long been positioned for a senior Commission role, aided by his close relationship with Bjoern Seibert, the influential head of Commission President Ursula von der Leyen's cabinet. Yet according to two EU officials familiar with his thinking, Léglise-Costa may be playing a longer game. He is reportedly holding out for what he sees as his true prize: the position of EU Council secretary-general, the diplomatic post that coordinates work among the member states. He lost that race in 2022 to fellow French diplomat Thérèse Blanchet, but officials say he has not abandoned his ambitions for the role. The catch is that Blanchet is not expected to step down before late 2027—a wait that one EU diplomat dismissed as impractical. Another strong contender for the secretary-general position is Agnieszka Bartol, Poland's current EU ambassador.
The September reshuffles extend well beyond enlargement and external relations. Timo Pesonen, who heads the civil protection and humanitarian aid directorate, is also expected to leave before year's end, opening another influential post. The succession race for the financial services directorate has already begun in earnest, with John Berrigan's retirement scheduled for the end of September. Three names keep surfacing in conversations around the Commission's headquarters: Paulina Dejmek Hack, who was just appointed as deputy director of the financial services directorate and serves as the head of cabinet for Commissioner Jessika Roswall; Michael Hager, a trusted aide to Commissioner Valdis Dombrovskis; and Mario Nava, the current head of the employment directorate, though his promotion would trigger yet another vacancy.
All of those named in the reshuffle discussions were offered a chance to respond but declined to comment. A Commission spokesperson told reporters that the EU executive "does not comment on speculation regarding senior management appointments." The timing of these moves is deliberate. On September 2, the full College of Commissioners will head to Ireland for its annual retreat, a week after the traditional gathering of the heads of cabinet. Last year's retreat featured considerable team-building exercises following a period of internal friction. This year's official theme is simply "reflection"—perhaps a signal that the Commission intends to reset its internal dynamics before the autumn workload intensifies. The reshuffles, combined with the retreat, suggest that von der Leyen and her inner circle are preparing for a recalibrated leadership structure as the bloc faces mounting geopolitical pressures and the need to maintain coherence across its most sensitive policy areas.

Why does it matter that Koopman is retiring? He's one official among thousands.
Because in Brussels, one retirement is never just one retirement. Koopman's departure is the first domino. When he leaves, his job opens up, and the person who fills it has to leave their current job, which opens up another job, and so on. It's a chain reaction that reshapes who has power over what.
And Karnitschnig gets promoted because he's the best person for the job?
Partly, yes—he's well-regarded. But it's also about geography, relationships, and what the Commission needs. He's Dutch, like Koopman. There's a sense of continuity. And he's proven himself in a difficult role.
What's the real story with Léglise-Costa? Why would he turn down a major Commission job?
Because the EU Council secretary-general job is different. It's not working inside the Commission; it's the chief diplomat for all 27 member states. It's arguably more powerful and certainly more prestigious. He lost that race once. He's betting he can win it next time.
But Thérèse Blanchet already has the job. How long does he wait?
Until late 2027, according to officials. That's more than a year. One diplomat I read basically said: that's too long. Why would you turn down a real opportunity now to gamble on something that far away?
Is this just bureaucratic shuffling, or does it actually affect how Europe works?
It affects everything. These directorates handle enlargement, foreign relations, financial regulation. Who runs them shapes EU policy. And right now, with Russia, Ukraine, Serbia, the Middle East—the stakes are high. The people in these jobs matter.
Why are they announcing this now, in July, when nothing happens until September?
They're not announcing it. This is all speculation and internal chatter. But Brussels moves on rumor and positioning. Once people know the moves are coming, they start preparing, lobbying, making their cases. It's how the machine works.
