Can an intensive Dutch course repair Boris Dilliès’ bilingual credibility?

Brussels Minister-President Boris Dilliès

The course turns a promise made on Dilliès’ first day into a visible commitment. When the Mouvement Réformateur politician unexpectedly became minister-president on 14 February 2026, he struggled to answer Dutch-language questions at his first press encounter. He acknowledged the problem rather than contesting it, later telling BRUZZ that he owed Brussels residents a good command of Dutch and regarded that as essential.

Dilliès has said that he could once give professional presentations in Dutch while working for Wolters Kluwer, but that his fluency faded through lack of use. During eight years as mayor of officially bilingual Uccle, he said in a March interview with BRUZZ, he rarely needed to speak the language beyond an occasional Dutch-language wedding ceremony. He has since taken lessons, listened to Dutch-language radio and political podcasts, and described long compound words as a persistent difficulty. The residential programme in Spa, provided by the language-training organisation Ceran, is a more concentrated stage in that effort.

This would ordinarily be a modest piece of professional development. In Brussels politics, it carries institutional weight. The Brussels-Capital Region officially operates in French and Dutch, and its political architecture protects representation from both language groups. The 89-seat regional parliament reserves 72 seats for the French-language group and 17 for the Dutch-language group. Government formation also requires coalitions to be assembled within the two groups before they govern together. Dilliès chairs that regional government; he is not the federal prime minister, and language education itself is primarily organised by Belgium’s communities rather than by the federal state.

The distinction matters because the controversy is about political legitimacy and accessibility more than a formal language examination for the office. Dilliès leads a government serving both linguistic communities and represents the region in external relations. The official Brussels government website also lists him as responsible for research, tourism, foreign trade, bicultural matters of regional interest, prevention and security. His ability to understand Dutch questions and communicate without an intermediary therefore affects parliamentary scrutiny, media access and the symbolic standing of Dutch-speaking Brussels residents.

The sensitivity was heightened by the way the present government entered office. Dilliès emerged as the surprise choice for minister-president after 613 days of political deadlock following the June 2024 regional election. According to BRUZZ and NOS, he had not been the expected candidate and was asked to take the job only hours before being sworn in. The coalition agreement had initially circulated in French, while its Dutch version followed several days later. Together, those events created an impression among some Dutch-speaking observers that bilingual practice had become secondary precisely when the new seven-party coalition needed to restore confidence in regional government.

A second, broader frame came from BRUZZ’s Dutch-speaking readership. In a non-representative online reader survey published on 22 February, 90% of respondents considered Dilliès’ lack of Dutch a problem. Several responses presented bilingual leadership as a matter of respect and equal access. The result should not be treated as an opinion poll of Brussels as a whole, but it captures the intensity of concern within an audience closely connected to the city’s Dutch-language institutions.

There is also a less punitive Brussels frame. Former regional minister Guy Vanhengel, from the Dutch-speaking liberal tradition, considered some of the early commentary excessive, according to a BRUZZ political analysis. Other participants in the outlet’s reader discussion argued that administrative ability and willingness to learn mattered more than immediate fluency. Dilliès himself occupies a related but not identical position: he accepts that his Dutch is inadequate and that improvement is a duty, while resisting the suggestion that perfect bilingualism should be the sole measure of a minister-president’s competence.

The episode consequently reveals two realities at once. Brussels is far more multilingual in daily life than its constitutional French-Dutch framework suggests, yet that framework remains essential to the political security of its Dutch-speaking minority. Language is not merely ceremonial when residents need regional information, question ministers or seek public services. At the same time, a 60-hour course cannot by itself resolve longstanding weaknesses in bilingual administration across the capital.

What happens after Spa will matter more than the certificate. Dilliès has not announced a target level, an independent assessment or a date by which he expects to conduct a full political interview in Dutch. The practical tests will come in parliament, at press conferences and during negotiations inside the coalition. His course can demonstrate effort; sustained, unscripted use of Dutch will determine whether it changes the political judgement formed during his difficult debut.
