Attal says partner Séjourné would join him at Elysée if he wins French presidency

Gabriel Attal, the 35-year-old leader of President Emmanuel Macron's Renaissance party and the youngest prime minister in the history of the Fifth Republic, has confirmed that his romantic partner, European Commissioner Stéphane Séjourné, would move into the Elysée Palace with him if he wins the presidential election scheduled for April 2027. The declaration, made during a televised interview on LCI on Tuesday, has immediately reopened a debate about the boundaries between French national politics and European institutional integrity that has simmered since both men rose through the Macron system.

A commissioner's oath and a presidential palace

The core of the issue lies in the oath Séjourné swore upon taking office as European Commissioner for Industry and Entrepreneurship in December 2024. Every commissioner pledges to act in the exclusive interest of the European Union, neither seeking nor taking instructions from any national government. That obligation does not expire when a partner enters a national election campaign. Séjourné's term runs until 2029, two years beyond the French vote. If Attal becomes president, the head of the French state would share a private residence with a senior EU official bound by treaty to disregard French national interest when it conflicts with the collective European one.

Neither Attal nor Séjourné addressed the conflict directly in the interview. Attal was not asked about it, and both men's spokespersons declined to comment when approached. The silence is notable. In Brussels, commissioners' cabinets are accustomed to managing recusals on specific files where a member state's interest is at stake. But a structural, daily proximity to a national head of state is not a file; it is a condition of life. The European Commission's code of conduct does not explicitly forbid a commissioner from cohabiting with a national leader, but the spirit of the treaties assumes a degree of separation that this arrangement would test.

Two careers, one household

Attal and Séjourné have known each other since their twenties, both products of the same Macronite political generation. They entered a civil partnership in 2017, the year Macron won his first presidential term. At the time, Attal was a junior minister; Séjourné was an adviser at the Elysée. Both advanced quickly. Attal became government spokesperson in 2020, then budget minister, then education minister, then prime minister in January 2024, a post he held for eight months before Macron reshuffled after the European elections. Séjourné was elected to the European Parliament in 2019, led the Renew Europe group there, and was nominated by Paris for the Commission portfolio in 2024.

The pair separated in 2022, a fact that became public only after they reunited in 2024. Attal described the separation as a private matter but acknowledged in the interview that their careers have always run on parallel tracks. "We have always separated our careers," he said. "We are two public figures, but we don't put ourselves on show together ... we each follow our own paths separately." The claim is plausible as far as public appearances go. They have rarely been photographed together at official events. But the structural overlap is harder to disentangle. As prime minister, Attal chaired the Committee for European Affairs, the body that coordinates France's positions before Council meetings. Séjourné, as an MEP and then as commissioner-designate, was on the other side of the negotiating table.

The polling reality

For all the constitutional novelty, Attal's path to the Elysée is far from assured. Recent polling aggregates consistently place him third behind Marine Le Pen, the National Rally leader who has reached the runoff in two of the last three presidential elections, and Édouard Philippe, his former cabinet colleague and now leader of the Horizons party. Philippe has positioned himself as the more experienced, steadier centrist alternative. Le Pen benefits from a consolidated base and a fragmented opposition. Attal's advantage, youth, media fluency, loyalty to Macron, is also his vulnerability: he is seen by some voters as the incarnation of a Macronism they have grown tired of.

The Renaissance party has not yet formally designated its candidate. The selection process, likely to begin in late 2025, will be shaped by Macron himself, who cannot run for a third term. Attal's announcement about Séjourné may be intended to project normality and stability, a contrast to the drama of the past year. But it also hands opponents a line of attack. The far right has long portrayed the EU as a foreign imposition; a president sharing a home with a commissioner would be a gift to that narrative. The left, meanwhile, could argue that the arrangement epitomises the fusion of French technocratic elite and Brussels bureaucracy that they have criticised for decades.

Brussels watches, Paris calculates

In Brussels, officials are wary of commenting on a member state's electoral dynamics. The Commission's spokesperson's service typically deflects questions about national politics. But the institution has a recent precedent. In 2019, Sylvie Goulard, France's first nominee for commissioner, was rejected by the European Parliament partly over concerns about her parliamentary assistant contracts, a national matter that became a European one. The Parliament's scrutiny of commissioner candidates is rigorous. Séjourné passed his hearing comfortably, but that was before a French presidential candidate declared an intention to share a roof with him.

The European Commission's code of conduct for commissioners requires them to avoid any situation that could give rise to a conflict of interest, and to resign if such a conflict cannot be resolved. The code does not define cohabitation with a head of state as an automatic conflict, but it grants the Commission president, currently Ursula von der Leyen, the authority to assess individual cases. Von der Leyen has not commented. Her relationship with Macron is cordial but transactional; she will not want a French presidential campaign to destabilise the College of Commissioners.

What the treaties say

Article 17 of the Treaty on European Union states that commissioners "shall neither seek nor take instructions from any government or other institution, body, office or entity." The same article obliges them to "completely" refrain from any action incompatible with their duties. The European Court of Justice has never ruled on a case involving a commissioner's private living arrangements. Legal scholars in Brussels and Paris are divided. Some argue that the oath is professional, not domestic, and that recusal from specific French dossiers would suffice. Others contend that the appearance of independence is as important as its substance, and that daily intimacy with a national leader creates a permanent, unmanageable perception problem.

France's own constitutional framework offers no guidance. The Fifth Republic's constitution defines the president's powers and the prime minister's role, but says nothing about the president's household. The Elysée's operational budget covers the president's official residence and staff; a partner's presence is a private matter unless they assume an official role, as Brigitte Macron has done informally. Séjourné would not be a French official. He would be a Brussels official sleeping in the French head of state's bedroom.

A pattern of blurred lines

The Attal-Séjourné relationship is not the first time the Macron era has blurred the line between national and European personnel. Macron's first European affairs minister, Nathalie Loiseau, became an MEP and then chair of the Parliament's foreign affairs committee. His former chief of staff, Alexis Kohler, moved between the Elysée and the European Investment Bank. The traffic is two-way: former commissioners Pierre Moscovici and Michel Barnier returned to French ministerial posts. But those moves were sequential. The Attal-Séjourné scenario would be simultaneous.

Critics argue that the Macron system has treated the EU as an extension of French domestic politics, a place to park allies, a source of legitimacy, a theatre for French ambitions. Supporters say the flow of talent reflects France's legitimate weight in the Union. The distinction matters. If Attal wins, the question will not be whether a French president can have a partner who is a commissioner. The question will be whether the EU's institutional architecture can withstand the reality that one of its most powerful commissioners shares a private life with the leader of its largest member state by population and second-largest by economy.
