Belgium's Prime Minister: who appoints, who dismisses?

The King appoints the prime minister, but he does not make up the name: he endorses whoever has built a majority in the Chamber of Representatives. Only the Chamber can then bring that person down, through a no-confidence motion that names a successor on the same day. In the three Regions, the head of government arrives by other roads.

Article 96: the King appoints, the Chamber holds the key

Three articles of the Constitution are enough to understand the architecture. Article 96 says: "The King appoints and dismisses his ministers" (our translation). Article 106 limits its reach: no act of the King can take effect unless a minister countersigns it, and by doing so that minister takes responsibility for it. And Article 101 sets the counterpart: ministers are accountable to the Chamber of Representatives.

So the King signs, a minister countersigns and the Chamber judges. For the appointment of a new prime minister, the countersignature comes, according to Wikipedia, from the outgoing prime minister, who countersigns the order naming the successor; the successor then countersigns the appointment of the other ministers.

On 3 February 2025, the government was sworn in at the Royal Palace at 9 a.m., before the King. Fifteen ministers, prime minister included, and no secretary of state.

Is the prime minister elected by Belgians?

No. No ballot paper names a prime minister: voters choose assemblies, and from their make-up, after negotiation, the head of government emerges.

The office itself is recent in the texts. According to the Chamber's fact sheet, it grew out of practice, and the Constitution only mentioned it formally in 1970. Its powers rest more on custom than on law.

How does the prime minister's name come out of the ballot box?

Through a series of missions handed out by the King, none of them with a written basis. The formateur (the person tasked with forming a government) negotiates a majority, and it is almost always the formateur whom the Chamber finds heading the government afterwards.

Bart De Wever was appointed formateur on 10 July 2024, handed back his mandate on 22 August over the budget, then was recalled on 1 September. The agreement was signed on 31 January 2025. Close to seven months of negotiation between the formateur's appointment and the deal, for a swearing-in three days later.

Meanwhile, the outgoing government stayed in caretaker mode, with limited powers, until the swearing-in of 3 February. The roles of formateur, informateur and preformateur are detailed in the glossary linked below.

Does the prime minister chair the Council of Ministers?

The Chamber points out a nuance: unlike the Dutch "minister-president", the Belgian prime minister is not president of the cabinet, because the King has never formally given up his right to chair the Council of Ministers.

At most fifteen ministers, and an exception for the prime minister

Article 99 sets the frame: the Council of Ministers has at most fifteen members and, "the prime minister possibly excepted", as many French-speaking as Dutch-speaking ministers.

The arithmetic is simple. Fifteen seats, minus the prime minister's, leave fourteen places to share: 7 French speakers and 7 Dutch speakers. Without the exception, an odd total would make parity impossible. The exception therefore makes the cap of fifteen compatible with the equality rule.

It does not reserve the post for anyone, though. According to Wikipedia, no French speaker was prime minister from 1979 to 2011; the Di Rupo government ended that run in December 2011. A run, not a rule.

Who can dismiss the prime minister?

Formally, the King, since Article 96 speaks of dismissal. In reality, the Chamber. The text provides that the government hands its resignation to the King in two cases, which the Chamber must settle by an absolute majority of its members:

• it adopts a no-confidence motion that proposes, at the same time, a successor to the prime minister;
• it rejects a confidence motion, then proposes a successor within three days.

Without a successor, the Chamber cannot topple the government by this route. Article 46 adds that dissolution is only possible in cases where the Chamber joins in by an absolute majority of its members: the King has no right to dissolve it alone.

The detail of these mechanisms, with their history and the regional precedents, is in our glossary of government life.

Confidence of the Chamber: 81 votes to 66, on 7 February 2025

The prime minister appears before MPs with a government declaration, then the Chamber votes. The February 2025 debate began on Wednesday 5 at 10 a.m. and ran 40 hours without a break. The vote came on Friday 7 February, shortly before 2:30 a.m.: 81 for, 66 against, no abstentions, according to VRT.

The Chamber has 150 seats. An absolute majority there is 76 votes. The government therefore won 81, which is 5 above the threshold, and 147 votes were cast out of 150 seats.

Four heads of government, four roads

The title of prime minister only applies at federal level. The Regions have minister-presidents, each chosen under rules of their own. The table sets the four side by side, with one common yardstick: the number of days between the elections of 9 June 2024 and taking office.

The three Regions each get a few lines, at equal length.

In Wallonia, the government has eight ministers and was sworn in on 15 July 2024. According to Wikipedia, Adrien Dolimont was chosen the day before, after the signatory parties ratified a coalition agreement; the source does not say which body made the call.

In Flanders, the government has nine ministers under Matthias Diependaele, in office since 30 September 2024. He succeeded Jan Jambon, and all ministers take their oath before the Flemish Parliament.

In Brussels, the coalition has seven parties and eight members. Boris Dilliès was designated at the end of the formation talks, then took the oath before the Parliament on 14 February 2026, and before the King afterwards.

None of these procedures is presented here as better than another: they answer to distinct institutional architectures.

Why 239 days federally and 613 in Brussels?

The ratio is 2.6: 613 divided by 239. Brussels waited roughly two and a half times longer than the federal State, and seventeen times longer than Wallonia.

The sources consulted do not isolate a single cause. For Brussels, they describe a government that requires a majority in both the Dutch-speaking and French-speaking language groups of the Parliament, and a formation concluded after three days of conclave. They do not say that this requirement alone explains the length.

Rules, not judgements about people

This article describes mechanisms. It says nothing about the quality of a government or the choice of one party over another. To see which parties sit in the Chamber, read the article on parties represented in the Chamber. Their positions, topic by topic, are in the comparator, and the site's scores reflect a position on an axis, not a quality: the methodology explains the limits.
